It's that time of the month again.
Tonight, the Critical Mass swarm of bicycles share the road with cars in Miami and Fort Lauderdale. The event usually happens at the end of every month -- to represent the Miami Bike Scene in Miami and to inspire road sharing.
While the ride is one of the largest social gatherings in South Florida, drivers and cyclists are warned to be cautious. Critical Mass has resulted in injuries and even deaths in the past.
In Miami, the 11.5-mile ride starts at 7:15 p.m. Cyclists will gather at Government Center downtown at 6:30 p.m. to start the route, which goes through Little Havana, West Flagler, Coral Gables, Miracle Mile, Coral Way, Shenandoah, Riverside and downtown.
In Fort Lauderdale, cyclists will meet at War Memorial Auditorium at 7 p.m. More information is provided on their Facebook page.
Take a look at the map below for more information about the route.
