Today was Pi Day, and I almost didn't realize it. mental_floss has a post with lots of neat pi facts. I celebrated Pi Day by participating in a π Run, a 5K (3.14 mile) run - or walk, in my case - to help raise money for graphing calculators at a local high school. And then I went and had pizza and beer, completely negating all the health benefits. Oh, well. It was good practice for the Peachtree Road Race, which I'm hoping I'll be able to do this year.
