Climbing trees near the Big City park

You know you live in a foreign country when you define places that you go by landmarks that you know.  So the last park we went to I defined by a restaurant near by.  This park we define because it's one of the parks we go past as we walk to the mall named Big City.  I needed to buy some food for a friend's birthday and the kids didn't have school.  So we decided to enjoy the day and take the kids to the park.  While I went to Big City the kids played at the park and then decided once I got there to climb some trees.  They had fun and it's one of those moments when I see them playing I want them to have big trees that are in their backyards that they can build forts and climb anytime they like.
