I've always found big cities to be intriguing at night.
After I finished Officers Candidate School, I went to Fort Holabird in Baltimore, Maryland for 4 months of Army Intelligence officer training. I rented an apartment for the duration in a building located just a couple of blocks from Peabody's Book Shop.
Bars in Baltimore were required to serve at least one hot food item to keep their liquor license and they all seemed to somehow manage to avoid duplication. The bar near my apartment was a neighborhood gathering spot and served an outrageously good ham and bean soup.
Every day an old man would come through the area with a horse-drawn wagon piled high with a variety of fresh fruits and vegetables. He would ring his bell as he went along and people would come out to the street to buy from him. Occasionally on the weekend, local artists would display and sell their work along the sidewalk.
It was an eclectic neighborhood filled with interesting people that I thoroughly enjoyed.
Once in a while, I would go out late at night and just walk around that part of Baltimore. During one of these walks, a young boy about 10 years old appeared out of the shadows and started walking beside me.
William was a smart kid and we walked together around that part of Baltimore for a couple of hours. We didn't talk much, and when it got close to midnight, I told him I had to go home to get some sleep before going to class the next day. We said good-bye, I headed back to my apartment, and William faded back into the shadows.
I made many more night owl excursions in Baltimore, but I never saw William again.
