Visitor Reviews of Irwin Catskiing by Eleven
- Dave Hallman from Canada writes:
We wanted to thank you and all the CS Irwin crew again for the great time we had skiing with you and Billy. Truely a memorable experience. We really appreciated the way in which you both presented optional lines depending on the ability of the various group members and what they were looking for. That certainly added to the experience and made for a less regimented, more skiing with friends sort of atmosphere.
