I have a big box of patched tubes, another of tubes that need patching, and a third box of tubes that can't be repaired (or need a lot of effort to patch because I need to remove glueless patches first).

I've been seeing more punctured tubes abandoned on the side of the road. One was picked up by a clean up crew after a few weeks. The other two were picked up by me. They have very minor damage and got put in the to-be-patched box.
