According to Tim Nelson with MPR News, "Snow and heavy rain brought down a section of the State Fair's Cattle Barn roof Tuesday night, the latest casualty of a record-setting winter in the Twin Cities. Fair officials said they believe snow slid from a higher point on the roof and the weight proved too much for a south-facing section of the roof along Como Avenue and near the fair's coliseum. The collapse is believed to have happened shortly after 6 p.m."
"There were no animals or people inside at the time, and no one was hurt, although the wreckage landed on a handful of food trailers parked inside the barn for the off-season. The barn is used during nonfair times: it typically hosts some of the activities for the Minnesota Horse Expo, scheduled for the last weekend in April this year. The collapse appeared to affect a 40- or 50-foot section of the barn's roof, part of its brick exterior and some windows, which lay in pile of rubble beside the building. The 117,000-square-foot barn was built in 1920, and is one of the oldest buildings on the grounds."
