Canada. Main reason is because the U.S. is getting too much of a reputation of intentionally growing high fenced trophy bucks. I suppose if you could chase a big buck in the U.S. without having it "grown" behind a high fence and have a decent chance at getting one (Illinois, Kansas, Iowa all come to mind) then I would choose the U.S. However, I think odds are in Canada's favor for probability of bumping into a true trophy class whitetail without high fences. Manitoba, Alberta, Saskatchewan would all be my initial focus for researching big bucks.
