Great list jonnymac. I add to this a 4-6 ft. pole with a hook on the end for retrieving stuff burried in a dumpster.
Leather gloves help to pull out stuff that might be sharp or messy. I find dumpsters behind small businesses and
industrial parks to be treasure troves. Amazing what people throw away. Extended family stops laughing and criticizing as they benefit more an d more from the finds. Hopefully, they will learn the trade for when that is all that is available.
