For years we have had a mutual agreement with all of our neighbors that allows us to track a deer onto the other's property. Despite our recent frustrations with our neighbors that's started this whole thread, we have helped them retrieve multiple deer on our property and theirs and they have done the same for us. We have a had a good relationship over the years, which is why I do not get why they have been acting like they have been the last few years.
As far as people other than our neighbors coming onto our land for tracking deer, we are highly skeptical of them. Several years ago my grandpa had a group of men stop by in a pickup (with zero deer in the truck bed) and ask of they could go back on to his property to track a deer they had hit. My Grandpa allowed them to go back to retrieve their deer. When they came out of the woods, there we're two deer in the back of the truck and then men just drove off without stopping back at the house.
Anyway, I'd also like to mention that this post has not went in the direction I intended.
