As a teenager and still to this day I love roller coasters, in spite of the fact that I am terrified of heights. That scary feeling of excitement you feel as the roller coaster rises and rises before the big drop; that is what I, as an Americanista, feel today.
There's excitement for the fact that we are in a semifinal, two games away from the final. We're only four games away from possibly lifting the championship trophy. But it is that same scary excitement because America has been here before in the recent past and not been able to make it pass this very round.
