Although I am not Canadian (not yet, at any rate), I celebrated Canada day by not getting burnt. I know, seems like such a small way to celebrate (what, no screech?), but if you'd seen the burn I got two Canada days ago, well, you'd be applauding my efforts.
Huzzah for Canada! Thanks for not invading the lower 48 (or Alaska or Hawai'i). We'll see if we can return the favor.
