My girlfriend and I moved out to Colorado back in 2006 from Buffalo NY, so I know where you are coming from CategoryKing (love the Undead name too). We love it out here and can never go back to NY to live there again. In fact, we went there last month to visit my parents and it was horrible out there. The economy has really hit it hard. Anyway, CO is extremely nice, there is a lot to do, a lot to not do (if you do not like going out to bars and stuff), and the scenery is just down right gorgeous. We initially lived in Glendale, which was good, but where we live in Aurora is incredible. People mock Aurora and I do not know why, where we live is far more civilized than Glendale, and Glendale seems to be the more upper class area. Not to mention we have a Target right acros the street, Walmart and TRU in walking distance, etc. If you decide to move here, you will not regret it. Oh yeah, and while summers are hot hot hot, they are not the "you shower while you sit" style of hot like the East Coast has. As for winter, it is like Buffalo's, except no one here knows how to plow.
Oh yeah, Safeway is like the Tops of Colorado and King Soopers is like the Wegmans of Colorado. Of course, if you did not have either of those places in PA, you probably won't know what I'm talking about.
