A vocal duo called the Ditty Bops are currenly on a cross-country summer tour, and they're doing the tour on their bikes. Great idea!
Reading closely, they're accompanied by a Dodge Sprinter van to carry gear and to accomodate mechanical problems, poop-outs, feeling-bad days, and the like. I can understand that, given the cost of a missed show. But give them a gold star for making the effort. (No word on whether the Sprinter is burning biodiesel. I'd feel a lot better if it was.)
