By now I believe it is safe on our lake to take the snow machine out for a spin or "burn" as Kim calls it. It was probably safe back in December but I don't like to take chances. I cruised along the perimeter but not down the middle of the lake - which I suppose was just as safe but I will try that later on in the month. I got it up to 40 miles per hour which is pretty fast - I had my helmet on just in case. We got our Trail Pass to go on the trails up here - our machine is a 1996 which they consider "Classic" so it is cheaper.
