LOOK: NASCAR Pokes Fun at NC Bathroom Law

CHARLOTTE - Signs on the porta-potties in the parking lot at the Coca-Cola 600 NASCAR race at the Charlotte Motor Speedway in North Carolina on Sunday poked fun at the ongoing controversy in the state--and the nation--over a bathroom law that requires people to use public restrooms that correspond to their biological gender. 

Take a look: 

North Carolina Gov. Pat McCrory is in attendance and received a mostly warm welcome and cheers from the crowd. 

Update: The signs were removed.
