Most people tell us we’re crazy. It has been that way for a long time.
Our specific crazy starts about three years ago, in the summer of 2008. That’s when Isaiah led a coast-to-coast bicycle tour with a nonprofit called Bike & Build, which organizes cross-country bicycle trips to raise money for affordable housing groups. Ever since then, we’ve been dreaming of a Pan-American bike expedition from Alaska to Argentina.
The three of us are brothers and best friends from our time spent working and growing up on our family farm in Starkweather, North Dakota. This dream would be the adventure of our lifetimes. Irresistible. We had one chance to do it with the three of us out of school at the same time. We’ve taken the opportunity.
Each day is consumed with hard riding through some of the most spectacular places between Anchorage and Ushuaia, Argentina, our ultimate destination. And yet we ride with one eye looking homeward, to our local Lake Agassiz Habitat affiliate, which helps folks in need in eastern North Dakota and western Minnesota. We want to help build a house with Habitat when we return home next summer. We have met people from all over the world who have been inspired by what we are doing and are kind enough to donate.
What we are doing is not easy. Nothing worth doing ever is. We’ve already endured enough cold, rain, snow, heat, rough roads and big rigs to last us a lifetime. We love what we are doing all the same, not only for the daily blessings of a nomad photojournalist’s life on a bicycle, but also for the ultimate cause that binds us southward and, ultimately, home.
