thinking about going around the end of march.what should i bring,on off road bike,scuba gear ,boat?are there any good places to stay that dont cost big bucks?how are the marinas?

Do you really live in New York? If so, I doubt you would want to tow the boat all the way to south Texas!

If you want to scuba dive, go to Cozumel, Mexico.

i haven't been in a few years, but there are better beaches in FL. i don't think there are a lot of boater friendly marinas and bars/clubs unless you like to go bay fishing.
