My class is going on a trip to Washington D. What are some good ways for me to raise money if I’m under the age of 15? Taylor from Fruita, CO. Add your voice! Click below to answer.

They set up several drop boxes wooden bins where people could drop them off and some of the parents took them to the stores.
