Hell, I dont even have cable in my normal house. and no kid of mine would in their treehouse either. unless maybe if they got a job and paid for it.
I did have a pretty sweet treehouse when I was a kid. It was in Saudi and my parents hired this Filipino contractor that did renovations for normal houses to build it. He was quick to mock the ideas my parents had saying that the trick to a nice treehouse is to build it as you would a regular house, only smaller.
mine was just one room, but had this awesome slanted ceiling that he insisted on as the flat kind wear out quickly and suck when it rains. it had a wraparound deck with a railing. a door and window that closed and were lockable from within. i spent many many nights in that sucker. it was also how i met a partner in crime. it was set on stilts as few trees in saudi were big enough to hold one of these. it rose up above the walls that divided our back yard from that of our neighbour. who was this mormon guy from my class that i'd never talked to.
the treehouse ended up bringing us together for many exploits.
how about the rest of you? any treehouse stories from your childhood? are any of your kids lucky enough to have one?
