From CNN.com:
Accused mailbox bomber Lucas Helder told authorities he was planting pipe bombs in a pattern to show a happy face during his five-state weekend cross-country spree.
OK, that's just wierd. Also, he was doing a terrible job at it. Look at this map. Does that look like a happy face to anyone?
Incidentally, I've been to three of the towns in which pipe bombs exploded: Morrison, Illinois; Tipton, Iowa; and Anamosa, Iowa. I'm pretty sure this is the most interesting thing that has ever happened in all three.
Whoops, I forgot to mention Davenport. I've been there too. And I've driven past Mount Carroll on IL Hwy. 64, but I haven't "been there" the way I have the other four.
