Summer's behind us, but the Port Huron Recreation Department will be keeping things fun right through the fall with lots of classes and programs being offered up.  An open house tomorrow will see samplings of the programs available, with the city's Toni George telling us all samplings are for free. Everyone who signs in at the door will also be entered into a raffle to win a free registration to your favorite class.  The open house is from 5:30pm to 7:30pm at the Palmer Park center.  Call 984-9760 for more information
