I've been dreaming about fencing out a neighbor since I first started archery hunting. As a young lad I always enjoyed hunting where I'd see the most deer. This usually landed me next to and around a neighbors field. Didn't take me long to realize that I'd likely never kill a deer from such vantage points but at 13, what boy wouldn't enjoy just watching a field fill up with 50 deer every night? For context, the deer all bedded on my parents farm and just utilized the neighbors alfalfa as a destination food source.
Fast forward a few weeks, having the time of my life, the neighbor begins to drive the deer off the field every evening with his ATV. Sending his son out to do one lap just as the deer start rolling out. Didn't think anything of it at first but it continued. Almost as if they were watching for me, they'd blow the field off every time I was hunting. Now, 20 years later, the same boy that used to intentionally ruin my deer hunts has now become an archery hunter that unintentionally ruins my deer hunts. Doesn't seem to understand to concept of scent control, wind direction, and just blows the field off every night getting out of his stand. It's like a light switch and the deer know they're being hunted after the opening day of season.
My biggest concern with fencing this guy out has always been the possibility of creating super funnels which he can capitalize on as deer flank the ends of the fence. Another issue I had was the implementation of deer gates. Gotta have a way, for deer that make in into the field at night, to pass through one way gates so they can bound for cover with ease. It'd be easier if they sold me the field but that'd never happen.
