I always wanted a tree house, but my dad never built one. So my brother & I just played in the three trees in our backyard. We imagined they were so many different things. Way better then any tree house.
There was a super awesome pirate ship at a house near Snow College when I was there. I have wanted something similar ever since. Red Beards Revenge Pirate Ship Playhouse : Luxury Playhouses at PoshTots
would love to have a treehouse in the backyard for my future kids. great idea to have a main treehouse and having a fenced verandah type thingy around a second tree with a bridge joining them together :)
