Planning a NOBO from Harper's or S.PA line in a day or two, any updates on lack of water that would be helpful?
Camel up in Harper's Ferry, the water source at Ed Garvey is a steep climb down and back up. Gathland park is alway reliable as is Dahgren backpacker campground. North of Washington Monument State park I cant help you with. I have never had water problems on this stretch of trail, however.
