Yup, used rollers in Kaukana, Wisconsin, now called the Wisconsin International Raceway, with my nitro JrFueler and my BB/GD. I think they went to rollers because tracks like Lyons did and it made the rounds quicker, and insurance companies happy. Kaukana used a Chevy engine with a trans, so they could back-up the nitro motors to clear them out.
Auto trans didn't work or the B&M torque converters had problems too. Then of course the blower starters became the thing, but tricky because most of the TF car had the front driver cars way back with limited room for the blower starters they use now.
It's all too bad, because I miss the show of the 1/4 mile push start days with a turn-around behind the start line. The slow look at the cars, the cackle of the motors the length of the stands.
