I would get the exact facts on the land perimeter and submit this to the state and local police mitigating the complaint as groundless. You have a logged compliant against you and if you do not address it it will stand helping the anti's next time you are practicing your right to the second amd.

I would talk to the folks and let them know that they are at fault and you have submitted all the appropriate documents to law enforcement. I would also let them know you plan to keep shooting IAW the law and if they areusing part of you land for recereation, you need to advise them in writing to no longer trespass. You can them post signsalong the boarder of the property with them that hte land is open for HUNTING ONLY.

I wouldalso letthe fish copsknow as they will help you out in handling problems like this.
