The downside? There is a great need to walk AROUND the trees for fear of getting knocked out by a rapidly dropping pellet-like object, if you are at all anxious about ANYTHING randomly but fairly consistently dropping acorns are not exactly good chill out music, even very large people can go skating across the parking lot when stepping on a large group of acorns. They are not to be trifled with.
The fun thing? Next year you will be able to count the acorns that fall from the trees on your hands. They dump every other year.
But I have never seen them unload like this.
