This book is about Ken Kesey and the Merry Pranksters during the late 60's as they were taking LSD and taking trips (but literally and figuratively) while traveling through California and Mexico making a movie. They held acid tests for anyone who wanted to join them--sometimes with LSD and sometimes using only their movie and music.
This is an interesting book of the drug culture of the 1960's and the hippie culture. When people told their stories of their experiences with the Pranksters the book was fascinating. When Tom Wolfe tried to convey what was happening or people's experiences the book was confusing. My feeling is you had to be there to understand it. Not my scene.
