Say goodbye to “More to Explore.” Minnesota tourism promoters are ushering in a new slogan that focuses on “Only in Minnesota” experiences as part of their largest-ever advertising campaign. The revamped messaging unveiled Thursday kicks off a major push to get vacationers to spend their time and dollars in Minnesota after lawmakers significantly boosted the state’s tourism promotion budget. The ads run through June in 14 states and Canadian provinces. Six states are new to Minnesota outreach efforts. They are Illinois, Kansas, Missouri, Colorado, Montana and Wyoming.
