I'm in LA on business today. I was in a partner's office and looked out at the foggy city below. I was struck by the insane number of helipads on neighboring rooftops. Then I noticed the different numbers on them. Mostly the number 10, but a couple with the number 8. Who can tell me the number relevance of helipads?
