Crazy neighbor put up this barrier

[John Underwood]

Neighbor that has 100 acres freaks when anyone walks on his property.

Beside our fire pit is the top of a mountain that substantially drops off.

He just put up this barrier.

I'll probably get this surveyed to get the exact property line, but it is in this general location.

One is idea is too plant some compact evergreen trees that don't grow too high. 

Thoughts?

Sorry man, that sucks. 

Consider Prunus Otto Luyken - a compact, semi dwarf version of English Laurel. Very dense but not excessively high growing so your view can be maintained. Reasonably fast growing too. Rather beautiful for a hedge. Durable in full sun as well as partial shade. Not 100% sure it's suitable for your climate but likely is as it's not a fragile plant. 

Maybe his arrogance/ridiculousness will result in you making a beautiful enhancement? Best of luck
