I wouldn't worry about it hanging in a garage in Florida. Just give it a good cleaning after you finish all your rides there and are ready to put it up for the year.

If it is going to be somewhere that it might have to be taken down and moved, caution them about rolling it on tires that might not have sufficient air in them. The tube can be damaged rolling it without enough air and you might fill it up and it last long enough for you to get to the place were you least desire to have a flat.
