Observing Anderson: An "In God We Trust" license plate sight

Pulling into the downtown Post Office's ,arking lot, I see this car with In God We Trust plates idling in the drive while waiting for a parking spot to open. The driver's turban caught my eye. Red and sitting impeccably on his head. I assumed he was a Sikh. We do not see many Sikhs in Anderson. So in what God is he putting his trust?
