Decades ago in Tampa, within a week or so of each other, two WWII vets died. Their widows discarded their war souvenirs in the trash. Each had an unneutered artillery shell. Welllll, artillery shells don’t like getting compacted. The government and the media saturated the area with TV stories, newspaper ads and flyers to help people identify unexploded ordinance. I don’t recall any injuries but there were two garbage trucks totaled. (Probably a couple of sanitation engineers needed new pants.)
That is the only thing I’d consider giving away. I inherited some boxes of foreign ammunition for guns I did not own. I asked around and found eager takers.
Come on people! Share the ammo!
As an MP officer at Ft. Riley, I was friends with the EOD detachment commander. He told me of a time when a family in Junction City had found an explosive artillery shell in the attic of their home. He told me it was from the 19th century and had probably been there since the early days of the fort which had been established in 1853. They were able to safely transport it to the installation demolition range and blew it there.
