Mom and dad may call the shots, but on August 11, kids rule the day at Briggs Chaney-Greencastle Farmers Market -- especially with one of two family activity packs courtesy of today's deal. Pay $15 (regularly $30) for a family sampler pack that includes vouchers for four basic and two premium games as well as two tickets to the tented Kids Variety Show. Or, shell out $25 (regularly $50) for a full family pack good for four basic and four premium games as well as four tickets to the variety show. Both options also include $5 worth of farmer's market coupons. This Silver Spring-area market produces a healthy bushel of family fun, including a mid-summer costume parade at noon—and for 50% off, that's always in good taste.
