Out of the snowmobile shows in the States, this coming fall which one would be the best to attend, the most vendors or booths with the latest gear and snowmobile related equipment.
Don't go to west yellowstone.... It used to be the best and i skipped it for two years and now it sucks. I will be going just to enter the races but not for the actual show. Also i live 56 miles away so its not a big deal. I wouldn't go to it unless you want to bring your sleds. The only person there that was helpfull was Sly Dog, the people with the cable ice scratchers, and F Bomb. F bomb was by far the best thoe.
Haydays is huge, but mostly used stuff in the swap. There certainly are all the major manufactures there, and lots of aftermarket stuff.. but alot of the mountain riding stuff is lacking.
The Puyallup Wa snow show is the best for that stuff... lots of vendors and a great swap also. It all depends on what your looking for.
Haydays is the largest and most complete. Jellystone is a joke. I would have to dispute the statement about not much for mountain riders at Haydays. There is not a lot of companys that are'nt there or represented by a seller.
