Back in the 80's when I was a kid we didn't have any clothes, or money to buy clothes, so we used to save rocks... Then when they finally built the first school, we made uniforms from buckskin and tree bark, and had to walk 30 miles to the schoolhouse, uphill, both ways, through the thumbtack fields, barefoot... We used to love to walk in winter when the snow would get thick enough to freeze our feet and cover the thumbtacks... Then when times got tough, we would have to boil our treebark pants in water, after the whole family bathed together in the water, then we would eat the boiled bark for dinner... But, I always saved some dried bark and rocks and even thumbtacks, because I knew someday, that I would have to sell them to support my family, till they were strong enough, then I could sell my family... Because thats the way we were taught
