American college football is virtually indistinguishable from pro football, so it's more like a UK pro football match. Giant stadiums (stadia), insane fans, etc.

But the country is huge. Aside: Have I ever mentioned that when I was spending a lot of time in Germany, I was asked how big the US was, and I said, "About 4500km across," and was told, "No, you must be converting wrong, that's impossible."

That is my favorite xkcd strip ever.
