I completed the entire MABDR last July from North to South. We were able to stay in campgrounds the entire route without much effort. In PA there are several State parks along the BDR with OK facilities. Maryland has really nice parks that are within 20 miles of the BDR. The state parks get nicer going south and less expensive. I think they were around $30 a night in PA. IN WV we camped outside of Peterstown at a private campground, along the south branch of the Potomac, for $20 for all three tents. By the time we were in VA we ended up camping in a Nation Forest Service camp ground outside of Warm Springs the day we did Section 3.. We were able to complete section 2 the next day and stay in a private camp ground along the New River. The Butler Map was excellent for finding camp grounds.
