1: Skipping the last 20 or so km at the far end of Ruta Tres because it would mean getting drenched in a thunderstorm.

2: Searching/ not finding/ giving up on/ spotting from the road/ not then going back to Butch & Sundance's gaff.

3: Getting to Buenos Aires for Maradona's homenaje but not getting in to the ground to see it live.

4: Aconcagua: if time hadn't been pressing, I'd have stayed the night and seen the damn mountain the next morning.

5: Wimping out on the ride up Ruta 40... but hey, I'm a wimp, OK?

6: Not splashing out on a plane or boat trip ouyt to Cape Horn, after all those childhood dreams.

7: Shaving the beard off.

8: Not hooking up with Tim & Ruth back in Rio. For reasons beyond my control...

9: Time's winged chariot again, this time preventing me sidetracking to a biker-rally in the unfeasibly-named Choele Choel.

10:Last regret? Coming back? 

And what do these regrets add up to? Not slowing down to smell the roses. Banking on the fact that I'll be back to do this again and therefore finish the job properly. I hope I've learned my lesson.
