I was a little before your time as I was done racing carts by 1987. Regular track was with Midstste Kart Club just outside of Springfield Il. Yes, street races were the most fun, dangerous, and lots of people spectating. Not sure if the Witt, Il street race or the park race in Quincy were still around in the 90’s but they were two of my favorites. All kinds of violent shakes in a kart in very rough street asphalt. It was the only thing that mattered to me from age 9-17. Raced nationals with Scott Pruett, Mark Dismore and some guy they call Smoke. Wanted to take the next step to sprint cars but my parents did not see it that way. One last thing, two stroke motors were the only way to go and we hated the fact that lawn mower motors were used for racing.
