Lee and Jan Slagter of Woodbury visited the Ice Castles at Miller Park in Eden Prairie on Monday evening. The installation, which opened on Saturday, will be open until March 5, depending on the weather, and there will be a winter star party there this Thursday from 6:30 to 8 p.m. Each of this year’s four installations — there are also castles in New Hampshire, Utah and Canada — weighs about 25 million pounds.
