We hope to bring back trick or treat in downtown for 2022! The merchants and businesses want to see your costumes! Streets will be closed to vehicle traffic on 6th from Bennett to Dudley and on Meade from 7th to the post office just before 5th. The Historic Downtown Prosser Association works in conjunction with the City of Prosser and the Prosser Chamber of Commerce to host this family-friendly, safe trick-or-treating event in the heart of our community!
