I'm probably the only American here who is still living in the United States, but I loved to watch soccer, cricket, rugby union, rally racing, Australian Rules Football, and the other international sports I do, I watch it.
I am still a football fan (Packers) and a hockey fan (Les Habs!!! - Montreal Canadiens), but it is more interesting if you have that kind of opportunity to get to see what's out there instead of staying in the United States and watch boring sports like NASCAR anyway
