Ok then it's not just me. I was trying to find something in JH but couldn't find anything. JH has a "Cat Skiing" link on their website but its blank when you click the link. They do have heli trips it seems. But that's too rich for my blood this year.
From what I've read, the nearest outfit is 48 miles away at Togwotee Snowcat Guides. Grand Targhee offers catskiing too.
