One of the problems with the Boulder area is that it's low elevation and most of the area has high exposure to sunlight. You're gonna be working awfully hard trying to keep snow on the ground.
Denver does the whole Ruby Hill Rail Yard deal, but there are years when it doesn't open at all. This year is one of those years. When it's routinely getting up into the 40s and 50s everyday, you're not gonna keep snow on the ground.
