Pistons on the Square - November is a free morning car and motorcycle gathering on the historic downtown square in Georgetown, Texas, held around the Downtown Georgetown Square. Every third Saturday of the month, antique, classic, muscle and late model cars and motorcycles roll in to show off their chrome, paint and engines. It's free, it's all ages and it's a great way to start a Saturday. Stroll the square, chat with owners about their rides and soak up the small-town charm.
