@TheOneyouwerewarnedabout I’ve seen those You Tube magnet fishers guys on the canals bringing up all sorts of metal things from the bottom of the canals…damn how many decades do they go before draining the canals and cleaning them or do they ever do it? So much junk down there including bicycles, metal vehicle parts, weapons etc.

@cherokeepatti I remember years ago cleaning the Mississippi River. At the bottom they found cars,tractors and boats.

@MrBrownstone some people here in the USA will do magnet fishing off of bridges in various states and find guns, car parts, and all kinds of junk that has been dumped into the water, including car engines with oil floating out.
