Yeah, it's his yard and he can do what he wants with it. But it still
****es me off.

That's a very negative attitude... why do you assume there is nothing
you can do about it... perhaps the first thing is to have a discussion
with your neighbor... he or she might be very receptive to doing
whatever to alleviate your plight. But don't approach your neighbor
with a hardnose tude.
