The image was hosted on flickr. The previous picture in the set caught my eye. Hmm, that looks like AT&T Park. Huh, I was just there! Wait a second, the photo was uploaded was 4/19. I wonder if they took the picture the same night… The was the same night I walked around the park taking my own pictures. Spooky.
Scrolling back a little further in the other guy’s photostream, I can they were also at the Web 2.0 Expo. What are the odds?
