As if we needed another reminder that all the crosswalks on the beach section of Carlsbad Boulevard need flashing lights, we have this four-car pile up near the corner of Carlsbad Blvd. and Juniper Ave. at 5:15 PM, June 5, 2011. The Carlsbad Fire Department and Police were on the scene, but luckily, no one was injured. . . this time.
