So I am guessing that we have some people that collect data, and then others that sort through all that. God that job would suck so bad. They get to look through trash for treasure. They are pretty much dumpster divers. If I had that job, I would quit on my first day.
I dumpster dive because I think its utterly criminal to throw away perfectly working equipment. Revive, recycle, re-use!
{A whole lotta oil-debt can be paid back with a return trip from the dump and a bit of patience..}
The info-gathering nature of dumpster diving still impresses me, 40 years later. Peoples' trash-cans are an open door to their rear-end, if ya know what I mean .. Don't forget to WIPE, people!
