I visit Tecate, Baja California almost every month. There is a lovely town square where locals and tourists mingle. There is a foursome that plays dominos each month. During my visit last weekend, I asked them if I could take some photos. They agreed, and quickly resumed their game, not paying me any attention.
Here's one of my favorite shots. I converted it to black and white and added a slight sepia tone for a more timeless feel. I will bring them copies when I return next month.
