I grew up in Littleton and now live in Fort Collins. To say that Fort Collins is on the plains and more Wyoming than Denver is downright laughable. Yes, Fort Collins is about 55 minutes to the middle of Denver while Boulder is about 40 minutes. That being said, to say that the games at Invesco are home games for CU means that you haven't attended one. CSU does very well representing themselves in these games considering their fan size and recent football success (or lack thereof).
A considerable amount of the population of Fort Collins commutes to Denver everyday. Fort Collins is on the plains? Seriously? You should make it up sometime. Fort Collins is much closer to the mountains than Littleton where I grew up. To say that Fort Collins is the plains means that Provo is on the plains as well. Very similar in their distance from the mountains.
