Maine humorist Gary Crocker will perform at the Bell Hill Meetinghouse, 191 Bell Hill Road, at 7 p.m., Sunday, Aug. 20. Crocker heard his first Maine stories walking in the woods with his grandfather.  Crocker will arrive at Bell Hill via motorcycle accompanied by a mysterious party of four similarly mounted who are well known here in Maine.  Don’t worry, it is not the Hell’s Angels. There is no charge for the program, although donations are much appreciated.  Refreshments will be available.
