“I would bury several dozen of those high powered super magnets along with a couple rolls of pennies to mimic bullets, maybe toss in some fishing weights. And just to get more imaginative do the pipe bit but just use some 4’ ABS about a foot long with caps, toss all the above in and glue it up.”
Good thinking. I am getting lots of good ideas on this thread.
Guess I’ll be doing some extra digging this spring.
Choose your locations with care. This article reminded me of a thread I saw on some gun-related forum during the Clinton years. In that instance, someone had cached a rifle and ammo on a piece of wooded land that appeared to be completely secure. He'd check on the area every year during hunting season.
The third or fourth year, he discovered his cache site buried under a mountain of gravel, as a new road was being cut through nearby - the gravel was for use on the new roadbed.
I think he was eventually able to retrieve the cache, but this illustrates how a single cache cannot be relied upon.
