Wildwood is a resort city that is very popular with vacationers and tourists mostly from New Jersey, Delaware, Maryland, Pennsylvania, New York, and even nearby parts of Canada (particularly Ontario and Quebec) during the summer months. The year-round population of Wildwood of over 5,300 grows to as many as 250,000 or more during the peak tourist season during the summer. Its most notable features are its beach and boardwalk, home to the Morey's Piers amusement complex and Raging Waters and Ocean Oasis waterparks owned by Morey's Piers. The boardwalk features a trolley called the "Tramcar", which runs from end to end. In June 2006, its Doo-Wop-style motels were placed on the National Trust for Historic Preservation's annual Eleven Most Endangered List, described as "irreplaceable icons of popular culture." In June, thousands of recently graduated high school seniors come to Wildwood for Senior Week. During Senior Week, the graduates stay in hotels and rent beach houses in Wildwood where they party and participate in underage drinking.
