RE: 4 wheelers
"sort of" off-topic.....but.....
I just bought an ATV this year. I used to hike my food to my feeders....50#'s at a time.......nearly 1/4 mile. I bought the ATV for numerous reasons......but one was to alleviate having to do so much walking/hauling MYSELF....lol.
My contention is.....that I leave less scent in my area NOW......than I did when I was walking to and fro. My "honey hole" is fairly close to the road, anyways.....and the landowner has always been in and out of there with tractors.
I'm guessing your deer "might" get used to the ATV's......but I'm sorry you have to worry about it. Here's the bottom line. If it isn't your land.....stay OFF OF IT if you don't have permission. What's so hard about that? I think your neighbor is NOT teaching his kids a lesson that someone else MAY teach them.....the hard way.
