While walking down Orange Avenue today, the cutest little white Toyota Prius wrapped in Orange County Property Appraiser official logos and officialness rolled on by. Then another one. Then another. Prii. Lots of them. They were headed to the Amway Center for Property Appraiser Rick Singh's Earth Day event, at which he unveiled a whole fleet of 30 new green cars today. Look for them appraising a property near you.
