Hey LizBlizz,
Great to hear that you're moving to Denver. As it sounds like the decision is already final, I ll spare you my misgivings about the city. I grew up here and recently moved back from Wisconsin. It's a large city with sprawling suburbs of which Littleton/Englewood are two. Young professionals in the area tend to live either around DU or in Capitol Hill. This city has lousy public transit so if you don't have a car, be within walking distance of the school and buddy up with somebody who does have a car. Capitol Hill is where I currently live and its fairly chic, it has interesting bars, restaurants, pawn shops, bookstores, coffee shops and other things you might like. Groceries are spread out so keep that in mind. Also, Capitol Hill is close enough to downtown that you could (but I never do) walk to the great stuff that grad students can't afford like the two art museums, amazing symphony, performing arts center, sports venues etc. Traffic, particularly from Littleton, would be borderline unbearable but you needn't worry about driving in snow. Denver has over 300 days of sunshine a year and its summers, while less humid, are no less hot than Florida. There averages only three or so big snow storms but that only happens within a narrow window of time in the winter. If there is anything else that I can help you with, don't hesitate to post.
