Kesey's book is great. But then, so is the Marquez. I think you should read them both! I, too, have postponed Ulysses. I had an English Literature lecturer at university a couple of years ago, who admitted he had never read all of Finnegan's Wake, and he was waiting until he broke his leg or got sick or something, so he could read it with no distractions and no obligations to get in the way. I guess that's the attitude I'm taking towards Ulysses; my ordinary life is just too busy to take on a project of that size.
