I love how the OP cites the "extreme" weather on Mount Washington.
Uh, DUmmies? You do realize that Mount Washington is the highest point in New England and one of the highest points outside the southern Appalachians east of the Mississippi. Its weather (wind) is extreme because it sits at the convergence of three major wind/weather patterns, and the fact it sits as high as it does relative to those mountains around it also tends to create somewhat of a "wind tunnel" effect at the summit.
Then again, if you'd ever been there, you'd know that.
