Having never seen a snowmobile (We don't get many of those in Tennessee), I must ask how you ride these things without snow. Do they have wheels?

[Kirkwood]

Uh, no.
Makes is kind of hard to steer I would imagine.

Snowmobiles have a single tread over which you sit on top of on a padded seat and two skis in the front underneath a cowling for the engine. I have seen them run on grass but the basic design is meant for snow not dryland running. Not sure what the road surface this now former snowmobile pilot was on when he saw his demise. It was obviously easy enough to get up to a speed he couldn't stop from safely.
