My favorite race to watch at a NH race track is the ISMA Supermodifieds at LEE USA Speedway. The track has different corners at each end and the Supermodifieds really put on a show with both inside and outside passing.
The tracks on this list are the ones that I go to because there is a good chance of seeing some great racing. I believe that Lee USA and All Star Speedway have consistently the best racing each week.
