The number one complaint from landowners is that hunters use their property without permission, destroyed property, or did not obey their wishes. This is one of the reasons why many landowners no longer allow any hunting to take place on their land. Hunters who act in this manner give the sport a bad name.
As a guest on someone's land, you should do everything necessary to leave the land better than you found it. Always obey the landowner's wishes, leave gates and fences as you found them, and offer the landowner a part of the harvest as a thank-you.
Furthermore, hunting on private land without permission is not only unethical; it is considered trespassing which is against the law. As a responsible and ethical hunter, it is your responsibility to report trespassers to the proper authorities.
Minnesota's Trespass law states that no one may enter posted property or agricultural lands without first obtaining permission from the landowner. Note, however, that not all agricultural lands must be posted. For more information on Minnesota's trespass law, consult a current copy of the Minnesota Hunting and Trapping Regulations Handbook.
