Fill with water... Add a diving board...
Hire a gator guard and a python guide...
Have fun...
My Army Reserve unit used to go for annual training/ARTEP at Camp Blanding, the FLANG HQ post northeast of Gainesville.
We sometimes went swimming while there, at Sand Hill Lake.
We always had an alligator guard with an M16 sitting on the hood of the Duece and a half!
It was the ‘80s so the pythons hadn’t arrived yet, lol.
And stock with some good eatin’ fish!
