You've seen some hipsters riding them about Buffalo. Those big tire Fat Bikes.  The bikes sort of bounce in the snow and look like so much fun.  The bikes have dune-buggy tires and yet have a mountain bike feel.  Here's a couple fun video to inspire.

If you want to have a Big Fat Adventure with a friend you may want to check out the Crested Butte, Colorado ride.

According to the Wall Street Journal, this is THE ride for folks that want fun and a challenge.  Elevation hovers around 9,000 feet.
