Slot car guys?

My brother has a 1/24th scale 1/4 mile drag strip in his basement. Once a month we have drag race night. We usually get about 20 or so participants. I race an H&R chassis '69 Dart, a Parma chassis '41 Plymouth Coupe and my wife runs a Parma '69 Plymouth Road Runner. It's a fun hobby and relatively inexpensive, once the system is setup. There weren't any drag race slot car facilities in our area, so we created our own.
