There are many places in FL that are good for a free night of sleep. I call it camping but that might be a bit of an exaggeration. I just get off into a wooded area, string up and stake out a 10 by 12 tarp, and get in the bag for sleeping. The next morning I pack and leave. Anyone walking through my sleep-site the same day would not know I had even been there. DO NOT go over a fence or open a gate to get on the land. If "no-tresspassing" signs are posted, don't go on the land. IMO very few people are going to get up in arms about a cyclist using a few square yards of woodland to get some shuteye. On Highway 90 in N FL you will notice that vacant wooded areas in towns and near them are often surrounded by steep, man-made swale ditches, often with water in them, making it nearly impossible to get onto the land with a bike anyway. I looked up the tresspassing laws in Florida a long time ago, but I don't remember the details anymore. If people really do not want you on their land it will usually be posted and-or fenced, and you have to respect that. I do. As for the police, I don't think they really care about it unless they get a real complaint from a land owner. They have other things to do. You have to use your own judgement, and respect the rights of others and you should not have any problems.
