THE PLACE IS EVERYTHING Kelvin promised—and more. Dense rainforest crashes down from the hills right up to its back wall. Oregon-type sea stacks pop out of the surf to the northwest. Our lonely, palm-lined beach reclines to the southeast.

Wading across a tiny stream, we climb two flights of wooden stairs up the back. At the top, just to the left, is the first of two yellow-orange-and-green wooden stages for dancing, this one butting up to the jungle, the pitched roof sagging from the weight of dirty stadium-rock speakers. In front of that is a barred window where a mellow, crew-cut guy in his thirties serves just one brand of beer (called Poker) from a single, glass-doored Coca-Cola refrigerator.

A gravel patio stretches a hundred feet out to the end of the peninsula, with dozens of brightly colored plastic chairs arranged in circles on its edge. Farther along, the second dance floor cantilevers over the surf. The best spot is at the very tip of the patio, where rough-hewn benches balance on rock nubbins and waves crash, misting the air.

We are the only patrons today. The next evening, the place will be packed with Afro-Colombian locals who've stumbled down the beach from town—most of them dee-runk on rum, barefoot and dripping salt water, and ready to dance to salsa music that's loud enough to rattle my teeth.

But that's the second night. This is the first night. Kelvin, sitting at the very tip of the patio, has a lager waiting for me.

"So?" he asks. I lean back, take the first tug, and feel the syrupy 82-cent liquid tumble down my throat. It is the best equator-warm piss water I've ever tasted.

"Awesome," I say, unable to find a better word to describe that rare joy when reality lives up to a dream. Kelvin and I are not the best of friends, but maybe we weren't meant to be. I'm the client, he's the guide, and for the next couple of days we'll be easygoing boozers, each with a private room, neither verbally rehashing the tweaked details of what we've seen.

We can do that in our own minds, and I start right away, staring north toward Panama. What happened with the guerrillas? Are landslides common? Did I really need Chinese underwear? Big questions, but not as big as the one I ponder next: Why is the image of that mother and son rescuing their air conditioner stuck in my mind?

The reason is obvious: That memory represents the spirit of the country. The mother and son are average Colombians, smiling, showing both the gritty pluck and animating hope I've seen throughout my journey—in Paula, Alessis, folks in the slides, even Flaco in his lead-footed way. All of them are trying to pull together a life amid Colombia's bigger landslide, the random violence of a civil war that ruins the lives of peaceful citizens everywhere.

Much to my surprise, I no longer feel a need to get blotto. Instead, with a sober mind, I'd like to continue processing, analyzing, and ruminating on what I've seen. And it strikes me that this change from passionate drunk to reflective abstainer is just the kind of personal transformation that's the reward of any adventure. It's an example of the power of a place to change a person, of getting far gone both physically and psychically, of looking in the mirror and wiping away the fog, and of the compulsion to blather on about your own shit in trite metaphors without ever feeling ridiculous.

Jesus, I hope it's not permanent.
