As far as rowdy, bike-based social events go: Critical Mass is old news. Even Nevius is all over it these days. While the now-monthly San Francisco Bike Party seems to be the current heir apparent, a darker, boozier cousin has emerged: The Midnight Mystery Ride, coming up on August 20th.

The details are largely undisclosed at this point (because it's a mystery), but adventurous cyclists can expect to ride somewhere starting well after dark at 11:30 p.m. on Saturday, August 20th. Judging from last month's ride, eager cyclists can expect the first half hour of that to be spent over a couple of beers at a local watering hole that will serve as the ride's meeting point. Those interested would do well to RSVP on the not-so-mysterious Facebook and await further instructions.

Naturally, we ask everyone to be smart out there in the dark and ride organizers encourage attending cyclists to bring their "camera, beverages and gnoshes, sense of adventure, lights and helmet."
