JEFFERSON CITY, Mo. (AP) — The Missouri Department of Natural Resources is keeping state parks open amid the coronavirus outbreak. The department will try to limit visitors’ interaction with rangers and other park staffers. State park workers will be on-site to answer questions and sign in campers. Signs will direct guests to restrooms and other services. The changes went into effect Friday in a move to curtail the spread of the coronavirus. Campgrounds, all day-use areas, boat ramps and trails remain open.
