While bicycling home from work along the Monon Trail on the Strida, the southbound traffic was held up by a group of bicyclists. One kept "singing" the Olympic anthem and all were happily noisily carrying on. As I slowly began passing them, I realized one had a big plastic torch held aloft.
Some had foreign flags, especially Spain's prominently displayed. Some called out to me as I passed. A girl between smaller groups hailed me with an offer of a medal for my exemplary bicycling; I took it: plastic gold medal with red, white, and blue ribbon. She said they were making house calls.
That's the first time I can recall seeing great enthusiasm for the Olympics in the US.
