This season, downtown St. Paul is turning into a winter wonderland, full of simple pleasures like twinkling lights and a giant rink open to all. Now through the end of the Saint Paul Winter Carnival, Rice Park will be illuminated each night with a flurry of festive lights strung from tall trees. Meanwhile, over by the Landmark Center, guests will take to the ice, where the rink will welcome casual skaters and hockey teams who reserve a time. Take a date or your family. Bring your own skates, borrow them for free if you bank at Wells Fargo, or pay $4 to rent a pair. For more info, visit www.visitsaintpaul.com.
