He’s gotta eat and have plenty of water. If he’s smart he would have brought a small fishing rod for trout in the streams.
That was my take, and it argued for him not being on Egmont Key for long. Any fishing would have exposed him to boat traffic, and fresh water was problematic. This guy’s a camper. A small wood-burning stove and mess kit, fishing gear, maybe water filtration, and he could hold out in the right area for a while. Not sure how he’ll pay for gas if he sticks with the truck. Panhandling, maybe. I stil wonder about the possibility of getting lost in an urban homeless environment. He probably wouldn’t like it.
