We were only there for a week, but we managed to visit St. John's, Gros Morne Park, Cape Breton, Halifax, Lunenburg, the Hopewell Rocks and Fundy Park. Kind of whirlwind tour of the east :) Mel's parents are still there visiting Prince Edward Island.
What amazed me the most about our trip was the people we met. Everybody we met was very friendly and helpful to us tourists. We were always greeted with a smile. Quite a contrast from Toronto where most people seem indifferent.
