Dear Helen (of troy) I once met a meteorologist who spent some time on Mt. Washington ... listening to his stories about the weather up there dissipated any small inclination I had to make the trip!
I'll make do with the video. The NH PBS station did a good program on the Mountain including shots of the station covered in ice ... and it wasn't even winter!
Oh, if you search for "Mount Washington+New Hampshire" in the quotes, up come several interesting links.
