I don't want to sound like an anal retentive bicycle killjoy, but this picture scares the heck out of me.
The photo, taken by Karen Ducey, appeared in Monday's Seattle Post-Intelligencer story about the annual Chilly Hilly ride. Because of unseasonably decent weather, some 5,000 bicyclists showed up to pedal the 33-mile ride on Bainbridge Island.
This is a long-time event (more than 30 years) sponsored every spring by the Cascade Bicycle Club, so motorists on the island are probably prepared to find cyclists weaving back and forth all over the ride's many steep climbs. The club reminded cyclists that the roads are open to traffic and to ride no more than two abreast. That can be a struggle on some of these hills, though.
