Tourism travel in Missouri is up slightly more than three percent this year, according to the State Division of Tourism. Tourism Director John Robinson says tourism heated up along with the weather, which follows a national trend to shift the start of summer vacation back about four to six weeks. The strength is coming from leisure travel. Robinson says business travel, on which he says the state can have little impact, has yet to rebound from the terrorist attacks of two years ago. He says the state wants to keep tourism on the upswing and will announce a new, fall promotion during the State Fair next month in Sedalia.
