I posted pictures of the snowcoaches in use within Yellowstone but I left one type out.  This appears to be the original design for snowcoahces and they are known as the Bombardier’s.  I assume this is because the Canadian manufacturer of snowmobiles was involved in their creation.  They have a cool body styling and they can get up some serious speed.  However, I understand that they are cold and rather uncomfortable.  Therefore, I was happy to watch some passing by rather than ride in them (although it might be fun to see how fast they really are).
