It didn't work very well because of the smooth tires. You would think that would have been a "no-brainer" but it should be noted that when Polaris first experimented with an all rubber track they tried "bologna skin" smooth conveyer belting and it of course didn't work either. Considering Skidoo had ribs molded into theirs for at least six years previous and of course the Russians had a one-piece molded rubber track with traction ribs on automobile conversions in 1911, the need for traction means would have been common knowledge. Regardless the Snow Cruiser was a failure and was abandoned in Antarctica where it still rests under the ice. In the 1950s an expedition located it and dug down to it. One of the guys who went inside brought home a stack of unused expedition covers (postal envelopes with official expedition markings) for a souvenier. Since deceased, his son was selling them on ebay a few years ago so I bought one. His dad may have been on the original expedition too because I think he sent me some photos from it that his dad had also. Strange concept. Almost looks like too many engineers were involved and no one with any common sense. No offense to you engineers out there. Remember the government was involved in this one.
