On April 22 the Toad Hall Bookstore on Main Street in Rockport is sponsoring an Earth Day Cleanup and children’s Beach Art Workshop on Front Beach. All are invited to walk the beach with naturalist Robert Buchsbaum and to create sculptures made from collected beach materials with local artist Nina Samoiloff. These events will kick off the 40th anniversary celebration of the Toad Hall bookstore. Activities will begin at 12:00 noon at Front Beach behind the bookstore.
