WidWed:Distortion

John and I got up at the wee hours of the morning and drove to Monroe, Washington, 30 miles Northeast of Seattle.  After he was done with business, we ate lunch in town, and came upon this statue of a chimney. Turns out Monroe has the biggest gathering of Vaux's Swifts in North America each September in a particular chimney in town. Thousands of them swirl around and fly into the chimney just after sunset.
This artist's rendition of the chimney (the actual one is down the street) is my feeble attempt at the distortion challenge. It's not my only attempt by any means. But if you look really, really carefully, you can see an ever so slight a curve on the chimney wall. I would not go as far as to call it a distortion, but it's more than any other shot had. Thank you Hobbs for your excellent tutoring on this.
