I remember quite a few of them, I had 2 1970 Olympics back in the early 70's and back in the 60's my buddies parents had bought a new 1968 olympic, They use to have snowmobile races back in the 70's at the Lewiston Fairgrounds on the 1/2 mile track so a lot of those cats, doos, poos motoski, Sno Jet, Skiroule, Alouhettes and Mercs were all prevalent, That was the boom of the snowmobile era where all manufacturers were trying to get into the snowmobile business.
