Did you go watch? That must have been fun. The Boston Marathon goes right by my street, and we (being the neighbors and I) always go down to watch at least some of it, and after a while, my hands get tired from clapping for everyone, but I can't NOT clap - by the time they get to me, they've already run almost 19 miles, and are just about to start Heartbreak Hill, so need all the encouragement they can get!
