No, it's just what they are called in Alaska and parts of Canada. That's all. Like Coke, soda, pop etc. I have heard Sarah refer to them as machines many times going way back. Todd has been a participant in that big "snowmachine" race up there for many years winning it a few I believe. Can't recall the name of the race but it's not that one with the dogs I know. :-)
it’s Iron Dog
There seem to be a lot of different levels of snow machines these days. You can easily spend $20K on a high end machine.
