Tracks he rode at in the 70's included Wendy Oaks, Tipton Hills, and Wild Country. He was with us almost every weekend since Marissa (daughter) started racing when she was 14. When she started racing he was so excited to be back on the mx scene again.

He raced in the late 70's, rode a Kawasaki. He has raced or rode ever since. Has mentored a ton of kids riding at his track too, gave advice and encouragement to them all.
