I'll chime in, though your planned day is already in the past. I don't have a jeep, but I have done a lot of dual-sport motorcycle riding in the Roanoke area. Get on 311 at Hanging Rock near Exit 141 of I-81. Drive north about 11 miles, turn right on Wildlife Road, a good forest road that goes about 8-9 miles and then connects to Broad Run. Left on Broad Run takes you back to 311 with several open fords, right on Broad Run eventually gets you to Haymakertown.
