We spent Canada's birthday watching America's favourite game... baseball. Our first time to a major league game for the kids and I (husband has been a few times). We watched the Seattle Mariners lose to the Boston Red Sox 1-2. My son was so excited and watched intently the whole game. My daughter, on the other hand, lived for the popcorn and ice cream. She would have rather been somewhere else.
This would be a great advertisement for "America's Favorite Pastime!" or anything related to baseball! Even a Nike ad! Couldn't you just see the Nike logo in the corner with "Just Do It!" on it! I can! :)
