I just spent a few days laid low by some virus or something.  So last night when my facebook friend Dallas posted this video, I watched it in its entirety (staying up a bit late in the process). 

It is a fascinating depiction of the Iditarod race across Alaska in 2001, especially focusing on the bikers.  Inspiring, but I still haven't signed up for the next race.  Slight language warning on this one.
