Okay - it has a couple minor conditions and the dates are limited, but hey.
This winter is the JH Mountain Resort's 50th anniversary. As part of the celebration, they are running a lift ticket special during the celebration period from January 11 to 31, 2016. If you show your valid season pass from any ski resort in the world, you'll get 50% off the daily lift ticket price.
It's worth a look, anyway.
