I like the rear-facing view - cool to see what your buddy is doing

Did you guys run studded tires for traction? Noticed your friend had his legs out most of the time...had to be tough on the leg muscles...lol.
Beautiful scenery; like all the snow on the trees. I bet it sounded really cool to have the 2T sound reverberate off the snow - probably nice and quiet when you stopped for breaks too.
