Underclass women join the fun - Freshman Balloon Day and Sophomore Hoop Rolling are two of the more elusive Play Day related activities. An article from 1922 mentions that the class of 1917 tried to participate in Play Day by "bringing out hoops, marbles, or balloons" both their freshman and sophomore years. Sophomore Hoop Rolling appears to have taken hold, becoming a short-lived tradition until the beginning of the Twenties. Freshman Balloon Day has even fewer records and may have occurred for only a few years in the early twenties, but seems to have been greatly enjoyed by those who participated.
