I was walking from where I parked today into work. There was an older gentleman with a cane behind me. As I was passing a breese way, he called out to me: "Young Man, do you have a moment?". I stopped and turned around and started back towards him. Then he said "I bet you walked past this every day and thought it was brick. What is this?" "It looks like wood", I replied. "You're right, this is an original wooden sewer from the 1800's." Then he said, "Make sure you share it with someone else." "I will", I replied. I reached for my camera, and took this picture. When I looked up, the man was gone.
