When I was a young boy we used to go hiking in the Adirondacks. My father would sling an ax over his shoulder and my mother and her three boys would set out on an adventure in the mountains.
We would come across leantoos. This is basically a wooden shack with a roof and one side open to the elements. It was shelter provided by the park service. We’d set up camp and spend the night.

I was the youngest of three boys and although these were really cool adventures, my brothers were 8 and 10 years older than me, so I used to complain a lot about all the walking.
Some of the places we visited had water falls and pools of deep, cold and fresh water. Because nobody thought to bring bathing suits, they went skinny dipping.
Now, don’t try. They’re watching from the sky.
Specialized spy satellites that can photograph things as small as a fist are flying above us. I can even see the junk in my backyard by searching Google Earth, and word is the governments have even better satellites flying at over 17,000 mph about 200 miles above.
