@glitterbag,
It is one very tall tree - the branches are way to high - probably why when the acorns hit they makes such a loud noise due to how far they fall. We would have to hire someone to be able to cut from that height.
My mom complains about cleaning up the acorns too - fortunately this is in the back yard so it is not as if we have to sweep up the walkway or driveway and we have enough creatures around due to the woods behind our house to collect them. It is funny in a way to see so many squirrels and chipmunks especially the chipmunks - I have never seen so many in one place before. I can walk out my deck and there are at least half a dozen at a time stuffing their cheeks. They run away and are shortly replaced by another group.
It drives the dog crazy though.
