Here's the post from their facebook page last night--
"Attention other resort pass holders. Present your 2011/12 season pass to any ticket window and get a 1/2 price lift ticket. Valid until the end of the season"
Not sure if that includes east coast or not, but it doesn't specifically specify "Utah pass holders". They also said half off night tickets until the end of the year-- no pass required for that deal, just show up.
