Today was the 5th annual Henry Vilas Zoo Run Run! It's a great course with a kid friendly crowd and the proceeds support the zoo – our favorite free thing to do in Madison. I walked the 5k route with some friends while Walter and Nate explored the zoo. They were waiting at the finish line to cheer us on, too! Next year, I think we'll let Walter participate in the kids event, the Roo Run Run. He might as well get his race t-shirt collection started early.
