Be thankful this isn't scratch and sniff.

This pinhole photograph at 28mm.org was taken at the same spot. Given the wide angle nature of the pinhole camera, while it looks like I was a few feet from the wall, I was in fact just a few inches away. For that photograph I'd put down my tripod and then knelt on the sidewalk. My mind thought "what is that smell" as I realized my right knee rested in a puddle of urine.
