I was entering data on my computer this weekend when I heard a big crash next to me. I ignored it. For about ten minutes afterwords, I heard what sounded like rain when it was sunny and very dry outside. Finally, my curiosity got the better of me. It turned out that a weed-wacker threw a rock into the window near me and broke it. The rain-like noise I heard was the window cracking. It appears to be safety glass or something. It's still standing, but very cracked. Anyway, this is a picture I took of it.
