I also remember an old 2pc unit called a Bolens that my friends Dad rode when I was a kid.The SnoCruiser was also a favourite back then but the Arctic Cat Panther Cheetah and Puma were nice tour neighbours dad worked for the Forestry Dept.and brought home alot of different machines for us to ride on. I remeber a SkiDoo Alpine with 2 tracks and one ski that took almost 40 acres to turn around.
