I grew up on the US-Canadian border and always found Canadians to be nicely different from Americans
Last summer I went to British Colombia pulling a 25'tralier and found the kindness offered to me when changing lanes to be vastly diff from what I was used to in SOFLA
And traveling in general I have ALWAYS ranked Canadians with Aussies and Kiwis with the nicest and MOST polite of travelers
Long time ago a bud and I were in France when there was a bank strike and we couldn't change our travelers checks(long before ATM's), 2 Canadians took our checks and gave us the going rate in francs, had never met us before and Unfortunately I never saw them again
