From Portsmouth Halloween Parade:

“Marching for the 31st time, the Portsmouth Halloween Parade is a grassroots, all-inclusive celebration of community, creativity and free expression that walks, stalks, dances, trumpets and drums its way through downtown Portsmouth each year on October 31st at 7PM.

Everyone is invited to dress up, gather at Pierce Island by Prescott Park, and march. No sign-up required. The Parade is NOT a city-sponsored event. It is entirely funded and put on by the community, which rallies a number of benefits to raise funds to cover expenses of insurance, permits and police escort. Hundreds march in costume, thousands cheer from the sidelines, it’s always a spectacle from either side of the curb.”
