Anybody know the story with the dude who walks down Old Hammond everyday?

I had to drive down Old Hammond to go to work every day for about three years. Most days twice a day(there and back for work and lunch). I noticed this middle-aged gentleman walking up and down Old Hammond literally almost every single day. Sometimes twice. Oftentimes holding an umbrella. I thought it odd, but he looked fairly normal, so I just assumed he was walking for cardiovascular reasons. Like recovering from a heart attack or something. No big deal. I wished him well.

Recently, however, I was in a big group, and the topic of conversation led to an area where this gentleman was brought up. And to a man(or woman), almost everyone had noticed him. I thought I was maybe the only one. Anyhoo, we got off topic, but someone mentioned that his story was featured in some publication recently, but I couldn't find it. This is certainly not meant to embarrass this gentleman or make fun of him in any way, but my curiosity is getting the better of me. If you know him and this is inappropriate, let me know and I'll delete. However, I am now fascinated by what his story may be.
