Historic Downtown Prosser Trick or Treat
October 31 @ 3:00 pm - 5:00 pm
Come trick or treat in downtown! The merchants and businesses want to see your costumes! Other groups will be in the center of downtown circled up for trunk or treat. 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 to host this family-friendly, safe trick-or-treating event in the heart of our community!
