It seems the majority of people I'd like to meet are no longer with us in the traditional sense. I won't completely rule out the possibility of ever meeting them so I'll include a few "just in case."
In no particular order, both the respiratory and the respiratory challenged:
Hunter S. Thompson
John Steinbeck ("No one wants advice-only corroboration")
Charles Bukowski
Dalai Lama
Ann Menebroker
Richard M. Nixon (I have some questions)
John F. Kennedy
Christiane Amanpour
Anne Sexton
Henry Miller
Jim Morrison (pre-addiction)
Ken Kesey (of course)
Anne Frank
John Lennon
Amelia Earhart (were you our pilot on that Vegas flight?)
William Randolph Hearst
Queen Elizabeth (Just what does she carry in that purse?)
