Hat tip to the Ironic Catholic.
As you can tell by the condition of this trailer, a contemporary Christian band known as the Flip Flops once played here - over thirty years ago. Instruments included guitar, banjo, upright bass, tambourine, and washboard. Then the synthesizer came in and wiped out the entire band. Same bad music, but now synthesized. Rumor has it there will be a reunion-slash-revival taking place right in this very field, in front of this very trailer.
