for the record I dont "look down" on the East in any way...I just dont think you can ever "compare" them.
I think this is an accurate comment.
Is eastern terrain as varied or have the scale of even midsized western areas? No
Is eastern terrain sufficiently varied/challenging that ski skills learned can be applied nearly anywhere else? Absolutely.
Are powder days anywhere in the East as frequent as the better places in the West? No
Are there some days when there is enough new snow and adequate terrain available to ski powder all day long? Clearly among the northern Vermont group, and with less frequency at some other eastern areas.
Again Mt. Baldy provides a suitable point of comparison. 3 of my top 10 lift served powder days have been at Baldy. So I totally get that a powder day on a similar mountain like Stowe/MRG/maybe Cannon can be as good as anywhere.
But the Baldy comparison cuts both ways. Baldy = best of the East in terms of terrain. But I would never try to argue that it's somehow better (or apples and oranges) vs. Mammoth/Vail/Whistler etc. just because it's my home turf and and I've had a few peak experiences there.
IMHO the easterners make their best case with respect to the powder days. The people in Vermont and probably Montreal should get more drive-up powder days than I do.
For the plan-ahead trips the case for the East is weak, due to
1) The significant probability ~1/3 of bad conditions.
2) The low probability of powder on any advanced planned trip, in which case the greater scale and variety of the West or the Alps become more important.
3) Several western areas still have much higher powder odds than anywhere in the East.
The reality is that skiers with a lot of flexibility in their schedules are overrepresented on FTO. The vast majority (even some of the nutcases like Patrick) have to plan ahead most of the time.
Thus the question I posed a few years ago in one of these threads: "If you lived in a region with no decent local skiing (Midwest, South) and were given 10 free plane tickets to ski anywhere, where would you use them?" If I could book the flight the day before I left, I might use one of the 10 to the East. If I had to book as much as a week ahead I would not use any to the East. Note that the transplanted easterners, who do know the potential of the areas when they are good, do not seem to be revisiting them very often. That's because in the real world you can't decide to fly in for a powder day on short notice, and they know all too well what they might get if they reserve too far ahead.
