We have a neighbor across the street and they have a really large tree in their front yard with like a gazillion leaves on it. Last year the owners only raked them up when their driveway was so loaded that it was slippery and the wind blew half of them on our yard, made me pretty grumpy.
The owners sold their home this spring and the new owners came and raked up their leaves from my yard!! How cool is that? And they have really kept up with keeping the leaves at their house raked so we don't have a mountain of their leaves on our lawn :)
I had 4 big black garbage bags of leaves from our own trees to take care of today, so I was extremely happy that I didn't have to add theirs to the mix this year!
