I'm a local. Boblett's Gap is a nice scenic fire road. It's pretty rutted out now, and there are a few places where you'll need 4wd.. It was pretty overgrown the last time I was out there, but it tends to be nicer in the fall like it is now when the leaves are changing colors. Pott's is cool, but definitely not stock friendly and not somewhere you'd want to go without someone who's got some experience there (and recovery gear)...
Broad Run is along the same lines as Boblett's Gap where it's mainly scenic with some water crossings. You have to be careful not to explore onto other peoples property... Unfortunately people ruined that concept over the years. If you take the Wilderness Road on 311, that eventually turns into Broad Run, which brings you back out to 311. It's a fun way to spend an hour or two and take in some scenery and maybe some wildlife.
I've been overhauling my TJ lately.. New battery over the last weekend, new radiator, thermostat, and now new rear brake lines unexpectedly. As soon as I get done with that, I'd love to get back out there if you want to run it sometime with me.
