I did some poking around under junk in the basement. I found a crate of 7.62mm I had put there "temporarily" about ten years ago, and then forgot about. Better than finding a misplaced $100 bill, although bills are easier to misplace.
When I worked at Nissan R&D, they had a yearly cleanup of all extra paperwork, and parts that engineers tended to accumulate. I watched as a document destruction truck ran around the clock, shredding paper. The car crusher (they had their own, so experimental cars could be destroyed on site) was kept busy, too.
After all the cleanup, I walked around, and couldn't tell that anything had changed.
Here’s hoping there will be an obvious difference, even to the most undiscerning eye, when I’m finished. Finding a case of 7.62, now that is way cool, can’t say I’ve found anything like that (yet). :-)
