Fall activities are in full swing with a pair of Yorktown’s upcoming markets in the weeks leading up to Thanksgiving. The November markets will be held at Riverwalk Landing. This Saturday, from 9 a.m. to 3 p.m., the Maritime Festival will be held. During the Maritime Festival, children can chat with pirates about seafaring life, join the Clan MacCool Band for a sea shanties sing-along, design their own wooden boat, decorate an oyster shell to take home, get their face painted, and bring home balloon art. At 10:30 a.m., there will be a chef’s demo with the Virginia Chefs Association and, at noon, there will be a Tea Dumping Ceremony at the Riverwalk Landing piers. The following Saturday, Nov. 21, also from 9 a.m. to 3 p.m., is the Harvest Festival. This autumn extravaganza features a live animal show, petting zoo, hayrides, crafts, balloon art, inflatable axe-throwing, and a pie-eating contest.
