I'm from that area and theres not a whole lot of on road around there. The nearest place is Redline RC in Marion, Illinois. www.Redline-RC.com
. I'm pretty sure they're still running on road, but off road is the big turnout. A lot of guys from Paducah come up to Marion to run off road. You can find out for sure on the forum.
I believe there is also racing down in Nashville, but I'm not sure if they're still running... and I don't know know their website off the top of my head.
For an even longer drive I think theres still a place running on road up in St. Louis, but again, I'm not really sure. If you wanna check out the Evolution Raceway site (gas track) and ask those guys they will be able to help you out. http://www.evolutionraceway.com/
Hope this helps, PM me if have any more questions.
