No, Robb, you're not insane. It does look like a model. I think it has to do with the weird depth of field effect in the picture. Usually, when you're focused on a subject as distant as the crowd at a wide angle, the depth of focus should be pretty deep. But the foreground and background are both quite blurry, as if it was taken at close range on a relatively fast aperture. Looking closely, though, I think it may really be motion blur, centered axially around the crowd, which leads me to ask if you took it from a moving vehicle (monorail)?
