My name is Don. Vintage Snowmobile Restoration Anonymous I first started showing symptoms of this very contagious disease in when I became the owner of a Arctic Cat Z. This sled was restored over the next two years and then I purchased a Trail Cat, restored it, and then a EXT. By this time it became quite evident that I was severely infected with this disease, with very little hope of being cured. To date I have restored 26 sleds and have rebuilt many others to be used as riders.
