I'm quite the 'word traveler', actually. Being stationed in Germany for a couple of years I skied all over Europe... Austria, Switzerland, German, France, Italy... I think maybe one in Lichtenstein?
I've skied in Alaska... and now my memory fades somewhat... for SURE: Nevada, Oregon... obviously all over Ca., I do not think I've ever skied in the "mecca" of skiing... Colorado... but I could be mistaken. Oh yeah, IDAHO.... not Taos N.M., on my bucket list.
In the east.. no idea, can't remember... but when stationed in New Jersey I skied a few times.. can't even remember which states.. NOT New Jersey, I don't think... I remember going up north so probably New York.
