I was reading an account of that Olympics. Quite amusing. It was the third one of the modern era, and it hadn't become a giant spectacle yet. It was originally supposed to be on the East Coast, but St. Louis managed to steal it away -- at which point most European countries decided to blow it off. In the end, only 12 nations competed, and something like 500 of the 600 total athletes were Americans -- except many of the 'Americans' were apparently European ringers. Norway is STILL protesting two gold medals they claim were won by citizens of their country improper enticed to compete as Americans.
By the way, setting that Olympics aside, and the one boycotted by Eastern European countries in 1984, the most medals ever won by the US was 110 in Beijing in 2008. That would be a good target to break this year.
