How much money do you have to spend on transportation? Where do your friends live in relation to the slopes?
if you're planning to visit a lot of other locales in the USA (places with and without ski slopes) then you will have noticeably cheaper airfare flying to the eastern portion of the US from Denver.
Snowboarding is cool and everything, but if you have the cash, then you should take a few days to visit New York City, Washington D.C. or any of the other touristy spots in this hemisphere.
Read on another forum: "If someone held a gun to my head and said, "You have to move to Salida tomorrow", I'd probably do it. If they told me I had to go to Breckenridge instead, I think I'd just let them pull the trigger."
