Bookstore also had a copy of Kesey's "Further Inquiries" about his 1964 cross-country trip aboard the bus Further. I thought I wanted this, until I thumbed through it. Changed my mind.
I'd already edited the wiki page on "Further (bus)" last week, to correct some misinformation and include what I'd learned from the "Magic Trip" movie, so the book would have had to supply new information. It didn't.
Couple days ago I received "Kesey's Jail Journal" in the mail, his kaleidoscopic notes on his incarceration in 1965 for pot. That was a fun purchase, although it's fairly short because the majority of his notebooks were confiscated and destroyed before Mountain Girl could smuggle them out.
