The rain seems to be over, but the ground’s still wet. So lawn chairs are better than blankets when you head to Festival Beach for the seventh annual dragon boat races. It’s all free, although you should count on the vendors for food. With martial-arts demonstrations, performances by many dance companies, and much, much more, every year this event grows. Each boat carries a steersman, a team of paddlers, and a drummer to keep cadence. I can’t find my pictures from last year, but this is a great take-your-camera event.
