Modified Girls Volleyball Special Guest Night

On 10/21 the Modified Girls Volleyball team hosted their first annual Special Guest Night. The girls had to think about a person at school that has made an impact on their life in some way. We were lucky enough to get each guest to attend. (some are not photo'd) They decorated the gym and made personalized cards for each of them. On top of that the girls closed out their season with a win against Hammondsport CSD.
