Non fishing would be a really tough choice.
In my impressionable and idealistic years I have had the privilege of meeting and/or speaking with the likes of Robertson Davies, Farley Mowat, the Dalai Lama, and McLuhan just before his stroke. All individuals of considerable intellect and insight. Pretty hard to find better intellectual company. Very much the opposite of some of my classmates now sitting in Parliament. They're not worth wasting lead or ink to acknowledge them.
I'm not so much of an idealist any more, and there are few in this world that impress me any longer.
Musically I would love to talk with Ian Anderson
Only others that would interest me would be the likes of Tom Hanks or Robin Williams. Fellas who can put me in stitches.
