Here’s one bad way to cool off over the long weekend. Last night, a 64-inch water main burst in a central area of Los Angeles, damaging cars, flooding buildings, and forcing residents out of their homes. At one point the water, which kept gushing for four hours, was three to four feet deep in the Studio City area. A portion of Ventura Boulevard will remain closed for another day. No injuries were reported, although one Southern California driver got a scare after his car was swept away and required a firefighter rescue.
