F4 California series season opener at Sonoma Raceway a few weeks ago with strong performances by Robert Arana, Andrew Davis, and Ana Palestro. Challenging few weeks before and after as my mom Barbara Jensen passed away peacefully at age 88. She loved car racing, and accomplished so much in her long life. Will be dearly missed by many, especially by her son.

Robert Arana pre-season testing at Buttonwillow Raceway with his three young race engineers Connor, Rafael, and Tyler preparing for the F4 California season open at Sonoma Raceway. He won their last year, and looks set to win his first race car championship.

Busy stretch continues this week next few weeks testing in California and Arizona. This week Ryan Spencer from San Francisco tested two days at Buttonwillow Raceway preparing to race in the F4 California series.
