Mercer, PA — (August 11, 2012) — Heavy rains over the last two days, and more rain showing on radar, have forced us to cancel the racing program for August 11. Excessive ponding in several areas of the pits also make it impossible to get race haulers in and out safely. Mercer Raceway Park greatly regrets having to make this cancellation, but once again, the forces of nature have conspired to prevent our racing program. A decision on the new date for the American Cancer Society night will be announced in the near future.
