Check this web site for contact info. Tom Bryant would be a good place to start.

There are several 'groups' pushing for some kind of track, some infighting among the various groups make the problem worse. I'm not involved with any of them at this point, to fragmented. SCCA hates the Drifters, dirt track guys could care less about anyone else, drag race guys don't need a road course, road course guys are super secret about their 'plans'. Whew, I'm buying a can of wax, screw 'em all.
When the track closed (land owner would not renew the lease) it got SO ugly the former lease holder burned down the track tower! Something about using a welding torch to 'dismantle' it, stuff happens, blah blah.
