The local .25 club says they can't run anyone over the age of 17 per their insurance... I tried finding info on USAC's site, but to no avail. They also mentioned tires, and something about the tires they run, and the scuffing or something we would cause to their track. Sounds like a bunch of smoke being blown in undesirable areas. Maybe someone can shed some light on this subject for me? Maybe it's a thing, but I think they just don't want karts at their track. Thanks in advance.
