Jack Chapman

Past President

I have always enjoyed the outdoors and soon after purchasing my first four-wheeler I realized I was hooked. I joined Cal4wheel in 2012 and decided to become a Life Member right from the start. I knew Cal4Wheel was very active in land use, as well as off-roading, and they played a large role in keeping our trails open, not to mention constantly fighting battles with those who were wanting to see all off-road land use come to a halt. Soon after becoming a Cal4Wheel Life Member I also joined Blue Ribbon Coalition and Nevada 4Wheel Drive Association, both as a life member.

Even though I did not immediately jump in and become overly active in Cal4Wheel, I did busy myself with a local club, Motherlode Rockcrawlers. Quickly after joining them I became president and served four years in this position. During my position of president, I had to pay attention to the desires of the board members and had to act accordingly. In accordance with the club’s bylaws, the president is not the one who makes the decisions but does have the responsibility of carrying out the board’s decisions. During my presidency I became involved with El Dorado National Forestry Division, local clubs, as well as organizations in order to complete the Deer Valley trail restoration. This led to the reopening of that trail for off roaders to enjoy. I must admit I enjoyed being president.

During my time as Motherlode Rockcrawlers’ president I became more involved in Cal4Wheel. I volunteered with multiple things such as helping transport the Win-A-Jeep, unloading and cleaning the Cal4Wheel equipment after events, transporting trailers, help in some of Ca4Wheel events and lately I have put many hours in at Cal4Wheel headquarters in Sacramento. I found myself wanting to become more active, so much so, that when Glenn Reynolds stepped down as the North District Membership I jumped at the chance and ran for his position. I was pleasantly surprised to have won as I am not well known to many of the members, delegates or clubs. Since becoming the North Distrct Membership Chair, I began learning how Cal4Wheel functions and in many aspects, I see room for improvement.

I believe in the ideas and dreams Mr. Morris had for the wheeling world, and I am honored to become part of this legacy. In my personal life I have a very demanding job that requires the ability to multi-task while staying on target in the timeframes given me. I supervise multiple people, negotiate with contractors, communicate with the public, resolve conflicts daily with employees and consumer issues, and report to both upper management as well as executive management. I would like to make a difference, so I have decided to run for president of Cal4Wheel.

Mike Magana

Central District Membership Chair

Hello, my name is Mike Magana. I am the newly elected C4WDA Central District Membership Chair.

I’d like to take some time to introduce myself. I grew up on a 40-acre vineyard in Raisin City, California where I learned the values of respect, hard work, and family from my parents, grandparents, aunts and uncles. We as kids earned everything (other than the basic essentials) by working in the fields; nothing was given to us because we wanted it (we had to work for it). I never thought that I was learning life’s lessons during that time. I just thought it’s what was expected being a member of the family (you did your part). After high school graduation went to Fresno City College for one semester (automotive classes), ran out of money. In 1980 I went to Alaska and became a commercial fisherman. That was a real adventure, starting with the long drive from Fresno to Valdez, Alaska along the Alaska Hwy. In 1982 I joined the Navy for six years, and got to see many different countries. After my Navy enlistment, I went to work at South West Marine in San Diego. I really enjoyed this job as an outside machinist. I started my carrier as a Correctional Officer in the infamous Corcoran State Prison, from June of 1987 until November of 2016, when I retired.

I joined C4WDA and Kingsburg 4 Wheel Drive Club in 2017. In that time I’ve had the opportunity to meet and work with a lot of great people and expand my knowledge of the OHV community. Since joining up with C4WDA, I am also a member of the Blue Ribbon Share the Trails Coalition and The Stewards of the Sierra. With the Stewards, I have assisted them in clearing many trails and campgrounds during the last few years in Madera/Fresno Counties. This year 2021, so far we’ve worked in Miami Trails area with Madera County, USFS OHV representative Ted Webb, replaced trail markers in Jose Basin, and started clearing some trails in Blue Canyon.

 I decided to take the next step and take a more active role in C4WDA and OHV. I never thought that being a member of a club or organization like C4WDA was a big deal, so I never thought about it, (I was wrong). Being a member is like being part of a large family with many different personalities and traits. Sometimes there are conflicts and differences of opinions. We are all one family and we need to stop the petty squabbles, and fighting amongst ourselves. No one should be here looking for notoriety and personal gains. We are supposed to be like a family, and C4WD is our family with local clubs being an extension of that family. We all should want the same things (keeping access to our lands open). We have the opportunity to really make a difference in OHV and we need to be united within ourselves as members of C4WDA and with other OHV organizations who share the same goals.

I look forward to being a representative of C4WDA and the Central District boards.  I will do my best to support and represent my extended family in C4WDA.

David Rocha II

David Rocha II

Central District Secretary/Treasurer

I grew up in the central valley working in the trucking industry and the ag farming industry; I currently run a small farming business. My parents are David and Nancy Rocha, who joined Cal4 in 1970 and have been going strong. I am a member of the Kingsburg 4WDC and the Broncos Unanimous club. I have been involved in four-wheeling and Cal4 my entire life. My family has always helped and worked committee for district meetings and events like Molina, High Sierra, Sierra Trek, Sand Nationals, Winter Fun, Hi Desert, Cal4 Convention, and many other local events.

You will either find me in an orange early Bronco or a silver JK whenever I can find the time to get out. I took this position to try to do my part to help Cal4 and the four-wheeling community. I feel that every single club and member needs to be heard and be involved in preserving the off-road community.

Danette Starksen

South District Membership Chair

My name is Danette Starksen. I have been married to my amazing husband Dirk since 1985. We have four wonderful grown children and four beautiful grandchildren (so far). We bought our first Jeep in 2014 after attending Easter Jeep Safari where I saw opportunity to go off-roading together instead of my husband dirt bike riding without me. We joined High Desert Four Wheelers in 2014 (Dirk is now the club President) and have remained active with Cal4Wheel ever since. We bought our second Jeep in 2017 and became Cal4Wheel Associate life members in 2018 with our company, Advanced Clutch Technology. I have helped with events such as Panamint Valley Days, High Desert Roundup and Convention. I love people, enjoy serving and volunteering with my mentor, Bonnie Ferguson. Like Bonnie, I don’t desire the spotlight and usually serve behind the scenes. I look forward to contributing to the future of our sport by supporting Cal4Wheel. See you on the trail!

Bonnie Ferguson

South District Secretary/Treasurer
Bonnie has been a life member of Cal4Wheel since 1974 and has served in numerous capacities on the board over the years, as well as chairing Panamint Valley Days and Conventions, helping with fundraisers and other events, and being a generous donor to the association.
