I enjoy any race amongst motorized vehicles. Lawnmower races can even be exciting. Semi tractor racing blows me away. Second to stock cars for me is the Australian V-8 Supercar series. It's like NASCAR on road courses. Maybe even a little better as the cars and drivers are dedicated solely to road courses. But all in all, NASCAR is in a class all by itself. Can I get an amen brothers and sisters? I used to love Supercross but I think the racing got boring once everybody went to thumpers. I even love the Soap Box Derby.
