haha, sounds like my family.
my brother and I would throw a pillow into a plastic laundry basked and climb in and push off, woosh, down the stairs we'd go.
you very quickly learned the perfect amount of backward leaning:
- too much and you'd thump down every step, you wanted the flat bottom the same angle as the stairs for a smooth ride.
- too little and the front edge would catch on the next step and you'd be sent flying headfirst
i'd be lying if I said this was even remotely close to the most dangerous stuff we tried, looking back I'm surprised we both survived into adulthood.
I will leave people with one last piece of advice though...rolling down a hill in a tractor tire is not as fun as you might imagine it to be.
this is why i'm glad i have two girls....
