Most Minnesota museums are already free to visitors, but even some that do have an admission charge will be free on Saturday, Sept. 29 as part of a national celebration involving more than 1,400 institutions around the country.

The Minnesota History Center in St. Paul and the Walker Art Center and the American Swedish Institute, both in Minneapolis, normally charge admission but will be free that day. The Minneapolis Institute of Arts, which is always free, is not participating.

Other participants range from the Rourke Art Gallery Museum in Moorhead to the Otter Tail County Historical Society in Fergus Falls.

Drummed up by Smithsonian magazine, the freebie is inexplicably dubbed "Museum Day Live!" The odd title seems to imply that museums are otherwise dead. Or suspended in some zombie-state. Or perhaps that museum visitors are less than perky. Well, never mind.Consider it a reminder to visit a museum.

There is a catch, naturally. For free admission to participating museums, you have to download a free ticket here at the Smithsonian site. Have fun.
