Very typical event here: Oh, a piece of rubber in the grass! Let's pick it up!
What the fuck. How long is this. Jeesus, I regret touching it now but I also want to keep going to see where it leads.
It went under the 1100 kg concrete beam, so I stopped there. Pulled out a few shorter lengths that were under this one.
It's old conveyor belt. There's lots of that here. Very tough and used as walkway on top of mud, which it sank into.
