With more than 4,000 cyclists participating monthly, L.A. Critical Mass claims to be the nation's largest community bike ride. On the last Friday of each month, cyclists of all stripes — from serious riders to families with kids — gather at Wilshire Boulevard and Western Avenue (last stop of the Purple Line subway) and roll out at 7:29 p.m. sharp for a casually paced ride through the streets of L.A. The event is intended for people of all ages with any type of bike. You arrive at 6:30 p.m. to get set, and the ride organizers provide support vehicles placed ahead of and behind the pack. These rides are a great excuse to explore different areas and meet bicyclists. It's also probably the only time you'll ride through a red light in front of a police officer without worrying about a ticket. Bike lights and helmets are recommended. —Chris Walker
