A campaign to boost funding for the state's natural and cultural resources will become more visible this month.
Minnesota voters will decide in November whether they want to dedicate a portion of new sales tax revenue to improving hunting and fishing habitats, parks and trails, water quality and arts programs.
Supporters of the proposed constitutional amendment will appear this month in dozens of parades and festivals across the state.
Ken Martin, director of the Vote Yes Minnesota campaign, says a phone bank effort is also underway.
"We want to talk to people who are still undecided on this issue. And we want to talk to folks all over the state and make sure that they know about this amendment being on the ballot and what's at stake," Martin said.
Officials with the Taxpayers League of Minnesota have criticized the proposed sale tax increase of 3/8 of 1 percent, and plan their own campaign to defeat the amendment.
