Well the neighbors on both sides of us are real good people and have no problems with this scenario. We can enter to retrieve downed gamewithout permission as they can on ours as well. They just need to make sure noones hunting at that time. They usually call first.But in most states such as Wi it is not required any longer to post your land with posted signs. All land in Wi is conidereed private unless other wise specified by the owner. such as state owned land, county land, forestry dev. land. You are tresspassing on everyones land that you enter with out permission of the owner. no signs needed.
