Memorial Weekend begin the fun Summer, and the July 4th weekend begins the "killing season."
School's out. Weather's hot. Kids with nothing to do. Inescapable heat and iritable folks with nothing to do but to hang on the corners and drink beer... Summer in the city.
Stay aware of surroundings and, as important, your own mental state. Keep one foot in the cool waters of your mind.
September will be here soon enough. Keep safe and enjoy.
