I think trying to make sense out of why people choose to ski where they do will drive you mad.
Take my area. My posting history on this board makes it absolutely clear that I love the place and think it is a special place to ski. But every day I come up to ski, I see a few license plates from places like California, Montana, Idaho, etc. California plates mean these guys drove past/through Utah and then added another 10 hours to their drive to come ski Wolf. Montana and Idaho means they drove through/past Utah, Wyoming, and every other ski area in Colorado to come ski Wolf.
I love the place, but if I lived in California, I am sure I would find a place in the 50+ ski areas I would drive past that I would love enough to save 10 hours on the drive.
Likewise, I am always mystified by the hordes of typical intermediate skiers that fly into DIA to ski Breck and Vail despite the crowds, when Copper and WP offer essentially the same experience for less cost and less crowds.
Or the intermediate skiers that want to experience fluffy powder out West and have Whistler in a snow drought year at the top of their list.
Or intermediate skiers that wasn't to experience fluffy powder out West so they can decide skiing out east is just as good where they aren't troubled by such things.
