For the past eight years, we have been saving (and even going out and collecting) anything that might one day be useful: PET bottles, glass, metal cans, cardboard, and paper. We had it all stored under a couple of Juniper trees to the south of our circle drive, but we decided to move it all to the workshop.
We made a few compartments, with roofs, to contain the junk and keep the wind from scattering it. Now, whenever we go to the shop to work on a project, we have everything we need close by - tools, materials, parts, and junk. It’s awesome.
