In 1965, following an arrest for marijuana possession and subsequent faked suicide, Kesey was imprisoned for five months. Shortly thereafter, he returned home to the Willamette Valley and settled in Pleasant Hill, Oregon, where he maintained a secluded, family-oriented lifestyle for the rest of his life. In addition to teaching at the University of Oregon—an experience that culminated in "Caverns" (1989), a collaborative novel written by Kesey and his graduate workshop students under the pseudonym of "O.U. Levon"—he continued to regularly contribute fiction and reportage to such publications as "Esquire", "Rolling Stone", "Oui", "Running", and "The Whole Earth Catalog"; various iterations of these pieces were collected in "Kesey's Garage Sale" (1973) and "Demon Box" (1986).
