Pindale Quarry Cave, c1982-85
The abandoned quarry was a favourite haunt of my dads when he used to get us out the house very early on a Saturday/Sunday morning to allow mum a lie in.
We were probably about 8-10. There was an active dig in the foot of the cliff with rails (John Beck was involved I think!) that dad had heard on the local grape vine had discovered some cave. So armed with yellow site helmets, (far to big), and crappy little hand held torches and our 1980s waterproof onesies, the 3 of us, Dad, me and and my sis, crawled in to explore. I cant remember much about the cave, other than we turned back and dad got stuck on the way out, we were behind him, so effectively trapped, one of our lights failed and the other was getting very dim and my sister cried.
In hindsight, it was probably mingingly loose and probably not where you'd want to take your kids.
First proper trip was almost certainly Giants with scouts (followed rapidly by Bagshawe, P8, Bar Pot to GG, Long Churn to Alum).
Happy days.
