Warning: there's virtually nothing about Ken Kesey in there. Also, her broad characterization of misfits as misunderstood creative geniuses is not only unfounded and probably inaccurate, it is repugnant to the entire ideal of the misfit that she herself is trying to cultivate; people that resist being categorized and sorted.
This is obviously a very personal story so I'm not trying to shit on it, but isn't "sneaking in" just sitting in on a class? Professors don't care, you usually don't even have to ask, but if you did it seems like most people welcome it. I turn up for talks at schools I don't attend, its not like there's security at the door.
