When the Parents Are Out of Town

I know I am going out on a limb here, but this is the kind of thing I would have done as a kid. As a parent, I am not so sure how I would have liked this though. I hope they have good Homeowner's Insurance. Bummer that we have to worry about such things. It does look like fun and what a great memory years later when they all get together.  I know, I know someone could have been hurt but it still looks like great fun.  Risky, but ingenious...enjoy!
