I knew this one... but in this neck of the woods, going to Canada is sometimes as easy as crossing the street! We have Timmy Ho's in Maine now- LOVE the maple! However, I liked both Timmy's and Dunk's doughnuts better when they were fried in-house... and I've always thought of a cruller as the popover of the doughnut world. LOVE THEM, but the Boston Cremes or Maple Longjohns are my favorites!
I'm originally from MA, so I say bubbler and soda... although originally we called soda "tonic." We call the shoes sneakers or by their trade name, as in "Are you going to wear your Nike's?" Don't get me started on mis-pronounced town names, including my hometown of Peabody (pronounced PEE-buh-dee)!
Local Maine foods... Lobster rolls (made in the hotdog roll that's split on the TOP, buttered on the sides and then grilled- YUM), clam chowder (WHITE, not red!), corn chowder, brown bread, steamers. Baked beans without tomato in them.
