Getting back onboard after rapids avoidance...the guy in the blue shirt is an aussie that i had seen biking up and insane hillclimb as our bus passed him the day before between Chang Mai and Thaton. He was a few days into a 2000 km bike ride through Thailand and Laos. As we passed him I yelled hello and he waved without looking up. When i met him before the boat trip I mentioned that i had seem him biking up a wicked hill the day before, and he says, "You're the lad that yelled hello, thanks for stopping!"
