In Ringolevio, Grogan discussed the 1967 Human Be-In, criticizing counterculture luminaries Timothy Leary,[6] Jerry Rubin, and especially Abbie Hoffman.

He objected to the "Summer of Love" enticing of young people to the Haight-Ashbury to experience hippie life, noting that an influx of residents would cause an "immigration crisis" and the kids who came expecting an already-formed Utopia would end up living a desperate hand-to-mouth existence on the streets.

[Ringolevio] is a hard-boiled, sometimes hard-to-believe, wildly entertaining tale that takes a totally unexpected turn when Grogan washes up in sixties San Francisco and becomes a leader of the anarchist group known as the Diggers.
