Art atop billboards

Missed the MAK Center's how many billboards in LA.

Update: Was wondering how I missed the billboards when I crossed paths with the art so many times...in the car that is. I'm rarely in a car in general. Guess I never looked up in LA. I'm fascinated by driving behavior in general. Everyone trying to talk to each other while muted; imagine trying to tell someone where you are going while covering your mouth. Little signals mean a lot. I also obsess over pedestrian behavior: are they walking for fitness, fun or work, with friends, where are they walking to/from, do they cross with the light? Enthralled by the few mixed-use retail areas. It seemed like LA lacks bus shelters though there are many bus riders. Finally, I literally count cyclists, check out their bike and see if they obey traffic laws. Total urban planning-transpo-geek.
