Cyclists are putting the pedal to the metal tonight for the 22nd annual Ride of Silence. Bike 305's Sue Kawalerski says it's in honor of cyclists killed or injured on public roadways. Miami-Dade police will escort cyclists on the eight-mile, double-lap on Crandon Boulevard for the ride which begins at 6 o'clock tonight. A four-mile, one-lap option is also available. Work's underway to improve the off-road cycling network with trail projects like The Underline.
