Riders John L. Wood, 39, of Eastpointe, left, and his father John A. Wood, 63, of Roseville, wait in the cold in Royal Oak for the 6:20 a.m. start of Friday's Ride to Work event, organized by Detroit Bikes! and Detroit Synergy Group. But the pair actually started earlier, riding from the elder Wood's home in Roseville to Royal Oak for the event.
