Numidias FIRST turn off is short. For some reason they want you to turn off there and not go to the top of the hill. So if you are trying to make that turn off, yeah, it is very similar to Island Dragway.
Atco and Maplegrove seem about the same to me, Maplegrove might be even longer.........
E-Town was just fine and there were several turn off you could take, unlike Atco or Maplegrove. The first one at Atco is pretty close to the finish line for a fast heavy car, and if you don't take it, all the way to the end you go!
I have had to get back on the gas pedal many times at Maplegrove if I wasn't on a full-out pass, which is typical when Bracket Racing!
