Join the club BigDaddy. That's kind of why I joined this site in hopes to find something. We have a couple local places, but it sounds like you've found those already. We've gone under 83 and all of that. We go to Green Ridge in Western MD. It takes 2.5 hours to get to the foot of the Mt., and it only costs $15 for a one year registration. We're also looking at a place down just above Harrisonburg VA.
JustinHEMI, I heard Michaux is not very well maintained but I've never been there myself.
