Last night was the 5th annual East Sac Nite Brite Bike Parade in Sacramento, CA. Hundreds of lit-up bikes cruised through the "Fabulous 40s" neighborhood in East Sacramento. There were several giant "Burning Man"-type bikes. One was a tandem quad made up like a toaster, one was a trike made up like a Roman chariot complete with merry-go-round horses, and the other was a high rise trike with electric hub motors on both rear wheels. The pedals drove the front wheel.
Here's video of the ride.
Some pics. The last 5 are screen captures from the video, so pardon the quality.
