The memorable tale of Emmett Grogan and the Diggers, the irreverent urban guerrillas and masters of street theater who made San Francisco's Haight-Ashbury a home. For anyone who thinks those were days only of peace, love, and flower power, "Ringolevio" will be a revelation, as it evokes the gritty urban sensibility that supplied backbone to the community's free flights of fancy. ". . . a great book".--Jerry Garcia.
