Great stuff man. Very jealous. I ended my three week tour two days ago, and I am in serious withdraws. You arrived in CO just as I was leaving. I really hope you make it this way at the end of September, and I can escort you down through Baja for a couple of days on your way south.
One piece of advice-
Lay off the McDonalds or you won't live to see South America.
Ride on man, ride on.
