They say if you’re good at something, you shouldn’t do it for free. Can the same be said for Minnesota’s new marriage law? Mayor R.T. Rybak thinks so—he hopes to turn it into a tourism opportunity.

After officiating 46 same-sex weddings Aug. 1, Rybak plans to invite other same-sex couples from around the country to hold their ceremonies in Minneapolis. MPR reports that the mayor heads to Chicago this week to launch an ad for his “Marry in Minneapolis” effort. Other cities on his campaign trail? Madison, Milwaukee, and Denver.

The Minneapolis Convention and Visitors Association is a co-sponsor of Rybak’s campaign. To ramp up support for this cause, the organization is offering free wedding planning services to couples.
