Stars and Stripes Dance Here's a strange, albeit sweetly romantic, image: ballroom dancers all dressed in red, white and blue, sweeping across the floor of a neighborhood community center on a warm and lazy July Wednesday afternoon. And all to the loopy sound of a live three-piece band. If you can see yourself in this picture, scrounge your closet for the right color clothes, bring a casserole, a side dish or dessert and don't forget your dancing shoes. 4:30-7:30 p.m. Spring Branch Community Center, 1721 Pech Road, 932-9573. $3 donation.
