The bane of my existence

As I noted in this post, I hate picking up all the "spikey balls" that fall from sugargum trees in my backyard each Winter. I just thought I'd give you an idea of how bad it gets. Please click on the pictures below to see them in maximum detail. The leaves have pretty much all fallen off the trees by now, so every little thing you see hanging from the trees is a "spikey ball". Eventually, I'm going to have to pick every one of those things up. I've got 5 trees like this in my backyard, as well as 5 more from another yard that have a significant amount of branches hanging over my yard.
