" I went camping with friends on the island off of Apollo Beach this
weekend,"

Do you mean "Beer Can Island"? I think the official name is "Pine Key",
but
Beer Can Island seems to be pretty prevelent. I caught a small hammerhead
shark there a few years ago, and the locals told me that hammerheads breed
in the area. Probably just a story to drive off the Yankee invader Pretty
good fishing right off the power plant at Big Bend, if you can keep the
catfish off your bait.

Yep, that's the one.
Don't know why it's called "Beer Can", it's been pretty clean the few times
I've been there.
All in all it's a pretty nice place to camp this time of year. I won't go
near it in the summer.
