At the OSU Homecoming Walk-around. Oklahoma State University has the largest homecoming celebration in the country. Every year sorority and frat houses team up to create enormous 'house decs'. The house decorations get very elaborate - it's amazing what can be done with metal frames, chicken wire and tissue paper! It was chilly, so Emma stayed curled up in the fleece carrier. It's too bad that you can't see her OSU outfit!
