I once passed Walter Cronkite in the Loop/downtown Chicago in the early 90's. I looked surprised when I saw him, when he saw this, he knew that I knew who he was. He seemed happy that I knew who he was by the smile and nod he gave me, with me being only 20 at the time. We nodded, smiled and never spoke a word yet he received the respect that I had for him. What ever happened to him?
