Now in its 43rd year, the MayDay Parade and Festival is one of the most riotous signs of spring. Revelers both young and old will march down Bloomington from 25th to 34th Streets. As they make their way, you’ll be able to spot crust-punk rockers on stilts, children dressed as fairies, giant puppets that take whole crews to maneuver, and friendly hipsters riding steampunk floats made of metal. There will be hippies, families, artists, and neighbors sharing in the joys of the spectacle and (hopefully) great weather. Festivities will then take over Powderhorn Park, where the Tree of Life Ceremony will usher in the new season. The party will also include food vendors, live music, theater, and info from local organizations. For details, visit hobt.org/mayday/parade.
