Connie, my science writer wife, and I have lived entirely on the road since April 2002. Some people think of us as homeless. From one perspective, that is true: we don't have a home. But from another point of view, we have dozens and dozens of homes. You see, we are able to sustain our itinerant lifestyle and evolutionary evangelistic ministry only because of the generosity of those who invite us into their home—and at times and locations that track our schedule of speaking events.

When we arrive at a new residence, we usually turn the guest room into a makeshift office. We set up our portable tables and lap-top computers there. Almost always, we choose to sleep in our van, which we call Angel. We have a bed built into Angel, above the storage bins. As our van is the one constant in our lives, we actually prefer to sleep there—no matter how lovely the guest bedroom—unless, of course, it is brutally hot or cold at night. Right now,...

in Scottsdale, Arizona, with daytime temperatures reaching 112 degrees, we have chosen to sleep in the van on only two nights out of ten. As I recollect, the coldest we've had to survive through a night was south of Klamath Falls, Oregon, when it hit 7 degrees F and we were enroute to California, so sleeping in someone's guest bedroom was not an option. Our missionary lifestyle—sharing the great news (gospel) of evolution in religious and nonreligious settings across North America—is so deeply fulfilling, so enormously life-giving, that Connie and I truly feel we are the richest people in the world. And we are! Think about it: we're perpetually on vacation yet always in the center of our bliss. We get to share a science-based reconciling, inspiring message to appreciative and ever-changing audiences. We stay with some of the most amazing people on the planet and have wonderful conversations about topics that really matter. Our hosts turn us on to their favorite waterfalls, woodlands, streams, botanical gardens, etc.—sacred places you'd never know about unless someone local told you how to get there. So we are falling more and more in love with North America (whom we call "Nora"?) every week.You can see where we've been in the past five years and find out where we are scheduled to be. Periodic reports on our travels, complete with pictures, can be found in our Turtle Log. Maybe we'll see you sometime on the road!
