Is it 1.2 miles round trip? If so, it is 2.4 miles round trip from McCormick Gap with about 500 feet or so of elevation gain. McCormick Gap is mile post 102.1 and you can access the AT there. Perhaps you should add this as a longer route option. Also, please specify that the 0.6 miles is one-way. Otherwise, good job.
"Got tight last night on absinthe and did knife tricks. Great success shooting the knife into the piano. The woodworms are so bad and eat hell out of all furniture that you can always claim the woodworms did it."
