Today I fully intended to finish my Christmas purchases and then wrap everything. I was in the car with my shopping list in hand when I had to stop for a passing train (I was so intent upon finishing my Santa shopping that I took the short cut to the mall. Well, it’s a short cut if there is no train). It was a long train, and after a minute or two I noticed there were a number of cool-looking graffiti pieces on the passing rail cars.
