I took this one wondering how often people look up. Walking back from lunch I was put at ease. I saw a man walking with his wife along the sky-way into the IDS building stop and remove from his pocket a small camera. He held it up and snapped a picture through the glass very much like my life capture I took not over half an hour before.
This was a fun one to take though. I had one person look up to see what I was looking at and turned her face down with a awed expression. The world is an amazing place.
