Good post -

Your neighbor's sanctuary is enough - BUT
you cannot hunt the border - OR you must regulate how you do and when.

Think of your border - kind of like an underground Shock Collar fence you see for dogs - the deer will, if you hunt the border regularly. Your "sanctuary" should be the corridor the connects your properties.

Still, you can set aside a section (5-20 acres) for limited hunting. It WILL help, especially if it butts up to your Neighbor that doesn't allo hunting - the size of your hunting group will determine if its a possiblity.
