The Main Event in Columbia
All Juniors and Seniors, as well as their dates, are welcome to attend P3, even if they do not attend Prom.
P3 is a fabulous party filled with top-notch entertainment, delicious food and incredible prizes in a safe and welcoming environment. River Hill has notably had the highest attendance of any of the Howard County high school post prom parties, with over 500 students attending in recent years. We hope for even greater success in 2020.
