I have not had ANY problems locating excellent places to hang on the FT. Pine trees are messy (sap), but they work. I haven't done too much of the FT south of route 60, but north of it I've probably got around 300 miles in and have never had an issue finding a place to hang.

I'm sure the spelling is horrible here, but Permethirn (?) works great! I soaked my hammocks in it and have yet to be peppered with mosquito bites on my back. You have to retreat about every 3 months, but it's pretty cheap and very effective.
