On this edition of “Will Rides The River Bed — Again!” this time I’m joined by my friend Andrew and together we did something that I think is pretty unique in the annals of Los Angeles cycling, we bridged the long (roughly 8-mile, as the water flows) gap from the southern end of the Los Angeles River Bikeway in Elysian Valley to where it begins again in Maywood, by riding entirely in the river bed between the two points.
