Yea...nice.. I see Yamaha won some vintage races here this winter at the Lancaster Snow Drifters Grand Prix.. one of the oldest snowmobile clubs in USA..
"The very first meeting of the Lancaster Snow Drifters was held on August 8, 1964 “for the purpose of deciding if all favored a snow-kart club.” This makes our club one of the oldest snowmobile clubs in the world.
The Snow Drifters incorporated on January 13, 1966 and joined the Northern NH Sportsmen Association on March 15, 1966 and NH Snowmobile Association on October 14, 1969."
