I have wanted to get a photo of this sculpture for many years and finally had a chance when I was stopped at a traffic light on the corner of 7th Street and Washington. That happens to be a very busy intersection with no parking on either street. In order to get close on foot, I'd have to park a very long distance away.
On this occasion, I happened to be first in a line of cars at the intersection with a perfect view of the sculpture. So I rolled down the window, grabbed the camera and took the shot.
This sculpture is called "Parabolic Spiral" and was created by Sam Sutton. He has another sculpture further up 7th street but it is also in a location difficult to get to. One of these days I'll get an opportunity to photograph it too.
