Unfortunately for my Mum she didn't know most of what we got up to as kids because generally we never got caught and yes home made explosives, cars (Roof surfing to name but one) and falling from high places to scare people were recurring themes.
I say unfortunately because as I grew to adulthood she was all too aware of the fact that I took up mountaineering and rock climbing. I climbed with the Australian team in foreign countries on 3 occasions and did a whole lot of other high altitude climbs with others. This combined with bungy jumping, white water rafting and travelling solo through Asia, Africa, Europe and Russia has left her with quite white hair.
Well at least thats what she attributes it to
My favourite kid story was when we used to climb up Jeddah Rock in the katherine Gorge and when the tourist boats came through we would wait until the guide told them the story of the young aboriginal girl (Jeddah) who dies at the end of Australia's first full colour feature movie by falling/being pushed (its left to your interperatation) from the top of said Rock. We would then jump from about halfway up the rock into the water and come up under the edge of the cliffs which formed a hollow that we could breath in. It looked to the tourists as if we did not surface.
The water levelis low in this pic so you can see how it looks hollow at the bottom of the cliff
