I've been reading the "Appalachian Trail Guide to Maryland and Northern Virginia With Side Trails" and I notice that at most of the shelters camping is not permitted. I was not planning on staying in the shelters, I was hoping to camp near or around the shelter itself. What about stoping any place along the trail and camping for the night? Of course we would practice "leave no trace camping". Has anyone had a problem camping at a shelter or on the trail in Maryland? Please let me know.
