Robert Stone was close to ground zero all throughout the Sixties. Kesey and the Merry Pranksters parked their bus, Furthur, outside his apartment when they finally made it to NYC. Stone was there and, since he is a trained novelist, he remembers it well. If you want to know where the Sixties came from and some of where they went, you can't do much better than reading Stone. If you want to know how a writer keeps on writing throughout it all, you also can't do much better than Stone.
