I never made it to pro level flat track. Just local events. Couldn't justify a purpose built flat track bike for the limited schedule in Central Florida at that time. I did build a trick TT500 a few years back, and was practicing at the local clay bull ring in Orlando. Still got my steel shoe hanging on the shop wall. One of the last ones Ken "Shoe Man" Maely made before he passed away. I did make it to the pro roadracing circuit in the eighties, first in the Battle of the Twins, and then 250GP. National #32 and FIM #508 in 85,85. Here's a photo of me in practice for the Daytona 100 mile 250GP race in 86.
The other photo is a professional dirt track motorcycle race at the Birmingham, AL. fairgrounds race track in 1916. You can see the Vulcan statute in the background. It now sits up on Red Mountain overlooking downtown Birmingham.
