i used my punching bag tonight for the first time in about a month. I couldn't use it before because it's outside and a bird decided to make a nest on top of it. And since i didn't wanna break the eggs inside or harm the baby birds, I decided to just not use the punching bag until they hatched and flew away. Well, they'd been gone for 2 days, so I decided to take down the nest and finally get some much needed exercise. This proved more difficult than i'd anticipated; when i shifted the nest a little, all this half-petrified bird poop fell out, it was sooooo nasty! So i had to get a broom and sweep like everywhere; it was a huge pain in the butt. Oh well, at least i spared the lives of 2 birds.
