8:40 AM | Lower School Halloween Parade (Anderson Gym). The parade ends in the Anderson Gym where parents are welcome! All students in preschool through grade 4 are welcome to wear "kid-friendly" costumes to school for this annual event. Please stay away from costumes that are scary, have weapons, or are inappropriate for school activities. Parents are welcome to dress up as well. Please note this is a very busy event and, as a result, the morning parking can be quite crowded and seating in the gym fills quickly.
