Hempfest is fresh like the springtime. Hempfest refuses to fly tie-dye flags fashioned from sheets. Nary a waft of patchouli flies over the Febreze-scented paths of Hempfest. The most contemporary elements of Seattle's music scene are showcased there. At Hempfest, organizers grab every political cliché by the nuts, give it a good hard squeeze, and make it fight badgers.
