When I was a kid, in moments of stress or elevated high jinks, my dad’s sense of humor rose. He was prone to things like putting grapes up his nose while my mother wasn’t looking to make us kids laugh. This was the camping trip to the Grand Canyon, when the clutch went on our old Jeep, and my dad was fixing it whatever he might have had at hand — a pliers and a fishing hook , maybe two rocks rubbed together in prayer, for all I know.

That same trip, someone was on the lam who had once also been a Navy Seal. We hiked into the canyon, passing sharp shooters at the rim. Don’t look, my mother said. Sometimes I wonder, Whatever happened to him? Did he have kids?

My parents never hesitated to get out our atlas, the essential road tripping gear. Looking at the map with my youngest recently, I chanced on Medicine Bow, Wyoming. We camped beside a man who lived in his canvas tent. While we were hiking, a lightening storm blew up, and my father hustled us down. As a kid, our sometimes peripatetic life was status quo, all kinds of living mixed in. I could list a 100 things without stopping that my dad taught us, all darn useful — like read Plato and follow water when you’re lost in the wilderness — but the one I keep returning to these days, now that I’m along in my life, is his utter persistence. A parent now myself, I think of him in the Grand Canyon with three young kids and a skeptical wife, with hardly any money and a broken-down Jeep. He patched it together. We kept on with that journey, thousands of miles, all those nights in the desert under the stars. At the wheel, he drove that Jeep for many more years.
