The other day myself and friend visited Buckden Gavel mine ( yes I know its a mine and not a cave but I am not on Adit now)
very interesting mine and worth a good look around when it is to wet to go down a cave.
We found numerous bits of rubbish, glow sticks, old gloves, bottles etc that we removed.
Not nice to find all this but now it is better for all those who visit.
Just thought I would share.
