Mt Biking has its advantages:  FAT TIREs will take you places that you would never reach on a road bike....
  FAT TIREs do require a little extra upkeep when the terrain bites back, which often happens when you
  least expect it!

  Below are some pictures of the carnage experienced on the FAT TIRE Challenge Mt Bike trail. 
    ***in all pictures, the Mt Bike and its rider were able to ride out of the woods on their own power
Snapped off the
  replaceable derailleur
  hanger
Fork crown broken and fixed with duct tape on the trail
Even 29ers flat out...here Travis helps Bill get his
  bike running again
Handle bar gash and bruise from endo
Rear derailleur realignment...single-speeds are
looking better everyday....
Gashes from
going down
hard into a
trailside stump
Pinch flats are common in the rock gardens!
Can you say "Faceplant?"
