I have a buddy who recently got stationed on an 87 out of JAX and he loves it. It was his first pick, and he couldn't be happier right now. I'm about to get stationed at HITRON on the opposite side of town, and it was my first pick as well. Most of the information I've gotten from people on units pertains to aviation, so I might not be a big help in terms of boats or stations down there, but I've heard great things about both Jacksonville and Savannah in terms of the places themselves. I don't know much about Pensacola. I'm sure there are a lot of people who can give you more specific information, but if you get through boot camp, and stay in for even a small amount of time you'll inevitably hear that everywhere in the coast guard is what you make of it. Take that to heart. Have fun.
