That way they don't need to call someone to tell you to leave. Hence giving you warning. REF: FS 810.02 (1) (2B)
Many states have adopted laws that do not require fencing nor signs to be posted; if you do not own the land and do not have specified permission from the owner to be on it you are guilty of trespass. If the land is fenced and/or has signs posted or the landowner has specifically forbidden you permission to enter, then you can be charged with trespass after warning. In AL, to hunt on someone else's property (actually, this applies to any time you carry a weapon onto someone's property) you must have written permission on your person or you can be charged with felony trespass. Like Mike said, if you do not own the land find out who does and ask for permission before entering, that will go a long way in keeping relations open to allow others on the property.
