Cyclists in Los Angeles effectively closed the 10 freeway in West Covina for about ten minutes on Sunday, as one of them proposed to his girlfriend in a cloud of pink smoke. Apparently, she loved it. The California Highway Patrol did not. The biker club members face possible citations including impeding or blocking traffic. LA Times has more. Looks like it was these guys, and the lovebirds have been identified by multiple local news outlets as Hector Martinez and Paige Hernandez.
SNIFFFFFFF. It's really good 'cause it's low production, anyone could have done it. Thanks so much to @janedevin for letting us know about it.
