Man and dog

I passed these two on the road earlier today.  I stopped to talk to the guy:

Me: "where are you heading?"
Guy: "Santa Cruz"
Me: "where did you start?"
Guy: "Santa Cruz"
Me: "Just out for a couple of days?"

Not quite.  Turns out this guy (and his dog) have spent the last 3+ years biking around the perimeter of the country.  The dog trots next to him as he rolls along.  They do about 20 miles a day.  I told him I was honored to meet him so close to his destination.  I feel like this trip has become my life and my job after only 3 months - I wonder what this guy will do after 3 years on the road.
