Yep they're getting better. When I first moved here ten yrs ago there wasn't very much technical riding there and just some short loops of single-track. It's now pretty fun and there are some nice challenging longer loops to do. Trails tend to get overgrown out there since there isn't much maint. but I'm glad it's there. Hopefully it doesn't get developed soon. The plan is for development, but they're also trying to work to keep open space and trails so we'll see what happens.
