Well confessed Bograt. I'm sure there will be a reward to anyone who brings your stuff out.
I'm afraid I believe it is up to the diggers to take responsibility for their own gear and make it known theirs is an active dig, rather than to put the onus on the Samaritan who might wish to clear it up. Look at that container of crap the Badgers offered to bring out of Nettle Pot.

It had been there over ten years and the contents were unrecognisable. The diggers actually told them to leave it there as they were thinking of returning to the dig. It was only because a third party intervened that the Badgers got the ok to bring it out, and well done them.
There is literally tons of stuff in our caves, taken in with the best of digging intentions and never removed (Notts 2 is full of it). We should not discourage those who wish to remove it.
