Despite the un-winter-like temperatures in early December, Mudd Field turned into a winter playground Dec. 1. Students skated on a temporary “ice” surface, a 30-by-40-foot plastic sheet designed to accommodate real skates. More than 125 students took a break from late-semester studies and took advantage of the activity. “I heard many students comment that the last week of the semester is the most stressful, and this was a good way to have fun in spite of that — if only for a few minutes,” said Leslie Heusted, director of the Danforth University Center. In addition to the skating and free hot chocolate, other activities available for the students included an opportunity to design their own coffee mug and make holiday ornaments.
