On those other sites, some of the posters must put broken glass on the floor along the other side of the bed. Then they make sure they wake up and roll out on the "wrong" side on this glass. They want to spend their day being mad.
In Kentucky, and most states I've lived, you must have the permission of the landowner to go on property without it being called trespass. The state advises the hunter to seek permission before hand or after. If permission can't be gained, the local CO should be contacted who can help mediate. As has been stated here, most states's CO's have the authority to go on private property with cause.
I support laws that require permission to "trespass". There are too many dishonorable "hunters" out there who will trespass with bows or guns in hand and them claim to be looking for a wounded game animal. In fact, they are often simply hunting without permission.
In fact, if my state sought to liberalize such trespass permission, I would attend the regulation meeting and oppose it. Something I have NEVER done as a civilian.
