RE: a little off season fun!
Dunno on the flounder--I've never been to the Gulf (I live up in the NE corner of the state). We shot the stingrays in FL a couple years ago (and carp are protected in FL--go figure--guess they are reserved for 'gator food).
If you ever get a chance to go for stingray, don't pass it up--even the smaller ones put up one heck of a fight! Pretty good to eat too, except the meat on the bigger ones is very coarse. When you get into the 25# and up range, use a bottle rig, or you are liable to loose your bow--did I mention they put up a fight?
