Ascot was cool. They had all types of racing, from demo and figure 8, to sprint and champ car, and all in between. JC Agajanian owned, which says everything.
Times GP was at Riverside, and if you sat in the bleachers in the esses, you could see nearly the whole track. That was an awesome track.
A friend raced flat track motorcycles at Ascot when I was about 18. Never went to Riverside.
I went to Supercross several times but the USGP at Carlsbad was my favorite motorcycle race.
