Darrell is a high school teacher and during the school year, he steps outside his high-school classroom for an outdoor walk whenever he gets the chance. His summers are spent driving the open road or walking backcountry trails in the nation's national forests and national parks.

His outdoor experience includes the Boundary Waters Canoe Area of Minnesota, the Yosemite backcountry in California, off-trail traverses in Glacier National Park, two separate trips through the geographic center of North America in Rugby, North Dakota, and a 2022 thru hike of the Appalachian Trail with his wife, Joni, and three teenage sons. "The heavens are telling the glory of God," says the psalmist. We all might as well go outside and see what, exactly, that means.
