I know you were sick.now you know how some of us think about the property line.
If I were you,before it happens again I would go to the property owner next door and introduce my slef and have a neighborly talk.ask him if you can trail a wounder deer?let him know that you are not part of the fude,or just talk with him.go with hat in hand and see what happens.if he says no then you will know what chiose you have.he may be understanding.

the property next to where I hunt was sold this past summer.I talked and searched until I learned who it now belongs to.a guy that most around this area says is a " REAL A HOLE" .I went to him and we had a talk about animals crossing the line. He was just as nice as any person can be. he said if something like that happens to me,by all means go after the animal.he also said there would be no need to try and call him , just go after it.

you never know how people will react to YOU!! Good Luck.
