Just completed a 3 day between US 321 and Damascus on Thursday, Friday and Saturday of last week. For anyone planning to be hiking in this area there is water at Low Gap US 421 at the piped spring next to the concrete picnic table. It is coming out about the size of a pencil. At Abington Gap Shelter the water is coming out of the pipe in the ground about the size of a pencil lead. Probably take 10 minutes to fill a quart bottle. Did not check Vandeventer Shelter. Suggest a cache at Tennessee 91 if you do not want to carry. Appreciate Roy at Mt. Rogers for the shuttle. I highly recommend these folks!! Nice to deal with , great parking, reasonable rates, good information, and a shower to boot! Leaves are all but gone after the small rain and wind of Friday night but what a great hike!
