A bit long but I found the concept interesting.
I have to gold machines that will process micron sized gold, the guy that I bought them from showed me vials he processed amounting to one troy ounce each, I asked a gold miner if he had any black sand I could use in those machines, he said that I wouldn't find any gold but I did find a bit, so I know the machines work.The ridges in those culverts trap placer gold or any heavy sediments. A creek near me has microscopic placer gold. Specks so tiny i need a magnifying glass to see them. On a hunch... went over in june one year, after spring rains. Filled sandbags which i placed across the lower end of a big culvert.
When the water was about 2ft deep I brought my small dredge over. Sucked up all the sands trapped behind the culvert ridges. Took most of a day to get about $2 in gold. Hey, can't think of a better way to spend a summer day than playing in a creek! and get gold!
Living in one? definitely not anywhere in the south... too many cottonmouths already live there.

Yep - not bad for short term gamma shielding/protection.I do keep them in mind while driving in case I ever get an 'take shelter immediately' warning over the radio.
I think it is worth keeping in mind. Having a few good preps in the car for such situations could be really helpful as well.I do keep them in mind while driving in case I ever get an 'take shelter immediately' warning over the radio.
Thermal and blast as well.Yep - not bad for short term gamma shielding/protection.
