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!
