Tyrol Basin is once again offering the Dark Dozen for those who like to ski and ride at night or perhaps can’t come out and play during the day. The Dark Dozen contains 12 transferable credits exchanged for 12 night session lift tickets good from 4-9 p.m. It saves up to 30-percent if you were to buy 12 individual nighttime tickets, and it is transferable. But hurry, the offer is good only through Saturday, Dec. 15. Log onto tyrolbasin.com or call (608) 437-4135 to place an order and slip over to the dark side.
