FEBRUARY 2005: After nearly forty years underground, the Sidewinder reemerges for the 2005 season under the watchful eye of the machine's original co-designer Dick Harrison. A veritable fiberglass boat on skis, the experimental Sidewinder was designed in 1965 by Trail-A-Sled to be a radically one-of-a-kind all-fiberglass wide track. Personal snowmobile of Trail-A-Sled, Inc. co-founder Stub Harrison, this massive machine was mothballed when the firm chose to use steel tunnels for its 1966 line-up of Scorpion snowmobiles. Ironically, the Sidewinder name would reemerge in 1981 for the final Arctic Cat produced Scorpions. Photo courtesy North Woods Images - All Rights Reserved. See Terms of use. Link to Home.
