Fertile prairie land and the Mississippi River put the Twin Cities on the map in the 19th century, producing tons of grain, milling it, and then transporting it to the nation. These days Minneapolis and St. Paul are more closely associated with arts and culture than gristmills. First-time visitors are often overwhelmed by the wealth of first-class museums and theaters in the Twin Cities. Minneapolis has also become a hot spot for architectural gems, including the Weisman Art Museum, the Walker Art Center, and the Guthrie Theatre. And lest Minnesota's reputation for harsh weather trouble you, both cities incorporate miles of climate-controlled skyways enabling residents and visitors to work, shop, and dine without ever stepping outdoors.
