Four directors of Rockland Historical Society, Larry Goldman, Dave Hoch, Gil Merriam and John Ware, will give an illustrated presentation about the Limerock Railroad, which operated from 1888 to 1942. Although only 13 miles long, the Limerock Railroad was very important to industrial transportation of the period. Free. FMI: 785-5444 and leave a message, or visit unionhistoricalsociety.org.
