I was on ex in Pensacola / Eglin AFB in the 80's. Spent 2 days wading waist/chest deep pushing a bergan raft. The problem was stepping on sunken branches which rotated and another branch would whack you mid thigh with no warning. Never so happy to get out of water in my life!What used to get me in Florida was when it was tourist season, “ah look love, an alligator go stand there so I can get a photo”. They look like they are huge lumbering things. The truth is they can go from a sloth like stillness to 15mph in the blink of an eye. Even Disney used to do regular patrols and checks of its lakes, and yet a gator got in and took that kiddy a while back.
