A drive-up burger joint in South Redding has sustained heavy damage from a fire that’s ill timed just as Kool April Nites is about to get underway. Pop’s 50s Place is a popular place for car enthusiasts during Redding’s annual celebration of automobiles. At around 11 O’clock Tuesday night Redding Fire Department was called when flames were seen coming from the back storage area of the South Market Street diner. Firefighters were able to hold the fire to the back room where it originated, but the whole building has substantial smoke and water damage. The value of the damage is estimated at $75,000 to the building and another $30,000 worth of contents. The cause has not been determined.
