David Jones is getting ready to roll. And everyone is invited to see him off.

At 10 a.m. Saturday, Jones will begin a 12,000-mile, clockwise bicycle journey around the edges of the nation. He’ll depart from homeless shelter Share House, 1115 E. 13th St., in downtown Vancouver.

That’s because Share, Vancouver’s chief provider of services and shelter to the hungry and homeless, is the point of his journey. Jones, a former Share board member, means to raise money for the cause as he pedals. You can help by visiting his website, Rolling Across America, where it’s possible to donate to Share as well as toward Jones’ own expenses. Or just visit Share.

Those expenses include video equipment — because Jones plans to conduct interviews and post them online. “I want to reveal in a very personal way what Americans think and feel about their country,” he says on his website. “I’ll be conducting interviews over these 12,000 miles and asking questions about each individual’s American experience, what they think and feel. And what are their challenges and solutions.” He’s even recruited Lisa Cicala, a Portland filmmaker and vice president of the Oregon Media Production Association, to rework his video footage into a feature documentary film.

Vancouver Mayor Tim Leavitt will stop by Share House to wish Jones luck. Members of the Vancouver Bicycle Club and the Share board of directors will join Jones for the first few miles as he heads out of town — across the I-5 bridge and east along Marine Drive. Day one’s target: Government Camp. After that, he figures, there’ll just be a year to go.
