Yep... there was a massive onroad track there as well, oval around the outside and roadcoarse through the middle, with a massive driver's stand.
Im trying to remember the exact years.. but I think i stopped racing there when I went away to boarding school for highschool, so that must of been the summer of 1990 that was my last. I raced there from 88 to 90 i think.
I actually remember when the track got transponders. When I just started there, you had 1 guy running the computer and manually entering laps, and a second guy would watch the cars and call out car numbers to him. After a while, we got transponders~! It was a huge deal... brand new!
