Legally Posted Private Land /Poachers

What exactly does this entail? A written notice in the paper each week? Here is what I have re Hunter orange. TIA Dealing with neighbors who love to shoot down our shooting lanes despite having 1000’s of acres

Q: I'm confused about the hunter orange laws. What is required on wildlife management areas and on private land?
A: WMAs: All hunters on WMAs including bow and small game hunters,(EXCEPT) waterfowl hunters must display 400 square inches of hunters orange and wear a hunter orange cap during open gun season for deer. Quail and woodcock hunters as well as hunters participating during special dog seasons for rabbit and squirrel are required to wear at least a hunter orange cap. Non-hunters afield during hunting seasons are also encouraged to display hunter orange.

Private land: Any person hunting deer must display on his head, chest and/or back a total of not less than 400 square inches of hunter orange during the open deer gun season including muzzleloader season. Persons hunting on privately owned, legally posted land may wear a cap in lieu of 400 square inches.
NOTE: These provisions shall not apply to persons hunting deer from elevated stands on property that is privately owned and legally posted nor to deer hunters hunting with bows on legally posted lands where firearm hunting is not permitted by agreement of the landowner or lessee.
