Loughman Lake Lodge is closed for now. The new owner has future plans that does include airboats, I don't know anything about the time frame though.
The river's getting a little low to come out of Loughman Lake into the St. Johns river without a pretty major hill run right now..we need rain around here pretty bad.
I do see campers at Hatbill pretty often.

Here on SA it's referred to as "The Kitty Camp" and you have to reserve it. It has a portalet, pitcher pump for water, grills, etc.. It's right by Hatbill...about halfway between sr46 & sr50.
