I think you have misunderstood this topic somehow. What are you reading that makes you think trespassing applies without a sign?
You may not be guilty of criminal trespassing and subject to fines and penalties where there is no sign but it is trespass nonetheless if you set up camp on private property without permission. I am not saying don't do it, just saying if you can get permission it is better and you can avoid embarassing consequences.
