When I was a scout in the 60's, I remember going on winter camp. We would pile into a school bus and head into the mountains (idaho) and stay in cabins the first night. The next morning we would head out a couple of miles and make camp. We would cut pine saplings to make lean toos and use the boughs to make the roof and bedding. Cut bigger trees to make fire wall to reflect heat into the leanto. Blaze trails to the latrine which was a deep hole with a shovel left to cover the waste after you did your business. I'm sure that camp of 60 or so scouts left an impact on the area. Oh how times have changed. BTW we had all the implements of distruction at our disposal and I had a set of throwing knives that I was professent with. (spell check all of the above).
