You are pretty much stuck with the rock as far as I am concerned. i have never had bad luck at Rockingham. Need to get there soon and run mine in the 1/4 again. You need to go further to darlington maybe or even into Florida. Bristol Dragway would probably be a good choice as well, but not sure what the schedule is. the only other 1/4 track that I know of is Fayetteville and I am not a fan of that place at all.

Good luck
