6-21-12 (Duluth, MN)  --  Following the heavy rains and flooding in northeastern Minnesota, tourism officials want visitors to know Duluth is open for business.  Visit Duluth President Terry Mattson says they got through the worst of the storm and are getting a lot of calls and emails for hotel, motel and bed-and-breakfast reservations.  He says there’s nothing that will hamper guests from enjoying Duluth for the rest of the summer.  Mattson adds that despite damage to some roads, about 90-percent are still open.
