If you analyze this carefully enough, you can see two people jaywalking in the middle of the road. If you can't quite see it at this resolution, perhaps a purchase of a 36x24 print (see links above right) will allow you to view this in greater detail.
I am told that jaywalkers pose a greater risk to public safety than rooftoppers. This comprehensive research study was commissioned by the BBQ Pork division of Rooftopping Inc. I made everything up...enjoy the photo!
