The city of Rittman will be celebrating the holidays this weekend.  Saturday’s Christmas celebration, which is meant to promote the city’s small business community, is being put on by the Rittman Chamber of Commerce.  The festivities will get underway with a Holiday Business and Shop Hop event, from 10am to 2pm, where shoppers can visit participating small businesses for a chance to win $100 worth of gift cards.  There will also be a parade with Santa Claus that afternoon, beginning at 4:30pm, and then a tree lighting ceremony that night at 6pm, on North Main Street.
