Thunder Road Speedbowl in Barre, VT is one of those tracks that is well run and will be around for a long time. And it's reputation for great racing is legendary. To distinguish racers, they list the state they are racing from next to the number...
I visited the track for a special weekend where the ACT, or American - Canadian Tour, series was racing and like Mohawk, it had an international flare. Many teams from surrounding states as well as Canada were in attendance.
There are difficult race tracks and then there is Thunder Road. To win here, you must gut it out the entire race. Side-by-side racing is both normal and expected. It'll turn boys in to men in a hurry.
