KERSHAW – Those searching for bargains and trying to support good causes can do both this weekend. A benefit auction for the Stevens Park playground is 7 p.m. Sunday at Kershaw Auction House on North Hampton Street (the old Center Theatre). Beverly Timmons, general coordinator for the Kershaw Community Park Council, said its members are looking forward to hosting the fundraiser. “All proceeds go to help fund the new playground,” Timmons said.
