Holy Cactus! Or is it Cacti?

Can you help us identify the location in this photo based on the cactus or surrounding plants? We hope that someone will be able to narrow down the date from the automobiles in the lot, or even uncover the identity of the man posing here.

Please leave a comment if you can tell us any information about this picture.
