Gentlemen
I appreciate your input on this matter. We have a long history with this neighbor and their continued adherence to "what's mine is mine and what's everybody elses is mine" is what prompted me to send the certified letter requesting they stay off of our property without our express permission. This occurred over a year ago after we had tried lets be friends, have a beer and sing kumbya. If the situation were reversed, prior to this incident, had they asked I would have let them retreive the animal. This neighbor also has a reputation with most of the other neighbors as being an ahole.
If this situation occurs again in the future I will call the local DEC officer and they will hopefully pay the fellow a visit and probably find an untagged deer hanging.
Be safe
