well I would contact the county records dept and ask for a map of the property and also a list of the adjoining properties, then you can get the names of them and ask about permission to recover a deer or, hell maybe even access
on these maps they will show the coordinates of the property, which if you own a GPS you can then walk it and mark it for yourself, just remember that hand held GPS's are only so so accurate, so allow for some gray area on your side to be safe
getting amap like this , here in PA they charge I think $20.00, but there good to have
we get them in the records dept in the county auditor's office
the county court house where the property is located is where I would go and ask them to direct you to right dept
I laminated mine then, there good to have on hand if you ever have to recover and a neighbor claims your on there side too, all the mroe so if a warden is called in!
good luck
