What about multi-time Loretta Lynn's 40+ champ and fellow Hoosier Larry Witmer? Just thought I'd let you know.
My father Al Silva Jr. ran the #27 for years in NorCal as a very well recognized Scrambles and Flat track racer. He raised one hell of a bad ass of a son, Mark Silva, who ALWAYS has ridden the #27 machine to numerous victories in the local races around NorCal, +30 pro class, vet this, vet that. He's a real bad ass, yo! Keep up the good work, Andy.

I believe Jeff Gibson’s number as an amateur was 27.
Attached is a photo of Jeff Gibson's Dad, Dan, who ran #27 throughout his amateur career. Number 124 on the SL70 is Dave Hand.
