which "Further" ?  by last count there's 5  and one still moldering out in pleasant hill  as of a few years back. i'm sure "family" still lives on his place....  kesey had a blast driving "Further" to the Smithsonian to to be  included in their collection...... and he was "waked" out in "further" also when he passed... 3 right there...
  he doesn't deserve to be put in a box as a druggie. he was much much much more than that. and to limit his legacy to that is disingenuous...like  "further"
