Atlanta traffic has mood swings like a sensitive person. Rain makes everyone testy, heat makes them feel charitable. A holiday weekend gets people ready to party. Sometimes this can make for interesting traffic. By Friday afternoon, many families had left town for a Fourth of July vacation. The streets were wide open. Everyone else was happy to be leaving work and ready to start the weekend. This made for some impatient drivers, and a few raucous young men who hollered something unintelligible at me. I never felt that there was any unsafe behavior though, at least not around me. And still more bicycles keep appearing on the road. Happy Independence Day!
