For those that don't know, the Watts Towers is a mini landmark in the community of Watts, in Southern Los Angeles County. And as we all know, San Andreas' setting is that of a San Francisco/Los Angeles city.
While examining the first 3 screenshots of San Andreas last night, I noticed odd looking towers in the background of the pic of the man crouching infront of his lowrider. I noticed they didn't look like trees at all. Then it just came to me that they were infact a replica of the Watts Towers. Here are some pics for comparison.
Just thought I would fill everyone in on this interesting find.
