“...they discovered multiple 27-gallon plastic storage totes that seemed very heavy.”
My son had an aquaintance helping him move.
“Boy these bins are heavy - what’s in here? Gold?”
“Naw - just lead. And some brass.”
One time a UPS driver commented on the weight of a delivery to me. (I don’t think he knew what ORM-D meant.)
“What’s in the box, lead?”
“Part of it is lead, yes.”
