NESBA AND CORNERSPEED. nesba because they have the schedule that works best for me. Cornerspeed because they are the safest, most organized track clubs Ive been too. In 5 yrs, I only saw an ambulance roll once. And to ride with them you need to have an accreditted school under your belt. The only drawback is that all thier trackdays are VIR or farther south. The big PLUS is they run the VIR GRAND COURSE!!
