The Americans start group play against France at historic Hampden Park, the only Scottish venue for the Summer Games. One can barely move around in London without noticing something that has to do with the Olympics, but the buzz in Glasgow just isn't the same. Some 37,000 fans are expected for the U.S.-France, Colombia-North Korea doubleheader in the 52,000-seat stadium, but organizers say about 80 percent of the tickets were freebies given to schools and local clubs because women's football isn't much of a draw in these parts.
