My buddies and I are hiking from Newfound gap to Fontana Dam. Typically we use our hammocks on other section hikes, but GSMNP has our hands tied on this. I am going to make reservations at the shelters, but if we get there and it is full, can we set hammocks outside shelter? GSMNP made it sound like that was not an option since we were not meeting guidlines for thru hikers. My buddies are freakin over staying in the shelters. They are even considering bivies. I think bivies would take up too much room. Any info would be appreciated. Thanks.
