Way back... actually I probably skied there more than that. Friend of mine, even older than me, and I used to go there every so often. We liked it a LOT. I don't remember it all that well, however, as far as specifics... what I remember well about it are the good times.
I don't think it's as big as China, at least not as many difficult runs, perhaps more runs. Also it wasn't that well known... at least back then, so crowds were light. My general feeling about... again "back then", was that it had that 'old time' feel to it.... like Badger near Yosemite. Today who knows?
Let me know how well your granddaughter did! - JamesJM
