thank you to guajira, to colombia. >> juan: to guajira. to guajira and colombia. salud. cheers.heers. i always find colombia encouraging. they've faced problems more extreme and seemingly more intractable than many of us can imagine. and yet, every time i come here, it gets better. don't get me wrong. problems, serious problems, remain, which is particularly heartbreaking in a country so beautiful, so generous, so proud, so eager to love and be loved back. i come back to my own country from colombia and i think, "if they could fix that, if they can make things better, then surely there's nothing we can't do." for now, however, i'll settle for fixing my headache. that hurt. ♪ [ dog barking ] >> anthony: so, i'm trying to understand buenos aires, and i've only got a week. ♪ ♪
