My brother is currently a student at the USAFA; it sounds like things suck pretty bad your first year there and they work you pretty hard all four years (like 20+ credits some semesters). It's a great school with a great reputation; I believe it was ranked like the #2 engineering school in the country. Colorado Springs sounds like a pretty cool place - lots of stuff to do, it's a short drive from Denver, and it is beautiful area. I remember my bro mentioning something about some French guy from one of the French military schools being in his squad, so there are some foreigners there. Good luck.
