I have a 12 pro 800 155, live in Saskatchewan and couldn't be happier with it. Sure it is too much for here, but we make trips to BC and it's 100% worth it. Go with the 155 if you are planning on riding the mountains, if not a 144 is perfect for the praires.
Spent the last 3 days here in vale sledding, first day we headed to Allen, found some good snow but vision was terrible. The next day there almost wasn't a cloud in the sky and nothing but sun, had an awesome time that day rippin it up in Chappell. It was nothing but 4-5 feet of powder or more...
I'm also booked to come mid December with a few others to stay in Elkhorn Lodge. Just wanted to hear your guys take on the snow conditions this year in Cooke City? From what I'm getting on the Internet things dot seem to be to great
