I've been caving in Yorkshire for a few years now having graduated in 2015. I've so far failed to find any quantity of young people. I have, of course, enjoyed the company of the more chronologically-advanced members of my current club, but I'm wondering if anyone can point me in the direction...

Anyone missing a mammut oval krab? Somehow left on the top of the entrance pitch swinging in the breeze. It's got two tape colours on it.
