The old Bakersfield sign has been gone for several years now but was very important to me as a youth as it always signaled that our family was almost to Sequoia or Yosemite and bound for a week or so of roughing it.
Bakersfield's economy is tied into petroleum extraction and refining. As we all know, petroleum has many uses other than just turning it into fuel. It was a little disarming to think that they had come up with yet another use in Bakersfield!
I didn't even ask for a sample!
