Okay, this isn't the same thing as the lady who blew her leaves into a freshly cleared yard but is still frustrating.
We have a neighborhood with quite a few trees. Everyone around us is really good about clearing leaves out of their yard. It is a constant battle because we all have trees that dump at different times but we are all pretty good about it. We know that we will have to clear leaves when our trees dump and when our neighbor's trees dump. All are good about it, that is, except for the guy behind me. He has two trees that dump relatively late and he never takes care of them. Mrs. Velo and I spent several hours cleaning up our yard for about the dozenth time this fall on Friday. All of the trees are nearly done so we should have just a little cleanup in a week or so. But the guy behind us has had pretty much his entire yard covered for a couple of weeks. Of course the strong winds last night means that about half of his leaves are now in my yard and our next door neighbor's yard. I am resisting the temptation to passive aggressively blow them back in his yard or go over there and ask him if he plans to ever clean up. I guess there will be matted down leaves along his fence next spring like there have been every year since he moved in. That also means that there will be a big collection of leaves on the corner of my property where two fences come together in the spring as well.
It's also a tree health issue. I know that on my maples and my next door neighbor's maples there was tar spot on some leaves this year. I don't know about the neighbor in question's maples, though. If the tar covered leaves aren't taken care of this fall the tar will be back and likely worse next year.
