Next week, three friends and I are hiking the AT through the Smokies. We have shelter reservations and a tarp just in case the shelters are full. But I really prefer sleeping in my tent. I like the privacy and the extra warmth. So I'm thinking of bringing my tent just in case the shelter is full. The downside is that since we won't be stopping to resupply, I need to bring 6 days worth of food, which adds weight, obviously. I know no one can make this decision for me, but I'm wondering what other's opinions are on this subject.
