Visitors to the Maine Wildlife Park in Gray can snap photos and get autographs of some of the Maine game wardens who appear on the Animal Planet TV show North Woods Law. The state fish and game department says the wardens will be at the park Thursday afternoon. Officials have received numerous requests for the event from parents of children who watch the Discovery cable TV program. Besides meeting the wardens, visitors will have the chance to see a couple of their K9s to learn more about them and their job. There’s no extra fee for this event, but regular park admission will apply.
