Sorry to hear that Ally.
Be careful as the Quarry’s have also had some activity in the last few months. Particularly when there have been Adventure Out type groups there. It seems with so many people in the quarry, you won’t know most of them and in a couple of cases when I was there, the theives walked into the group and opened the car doors (left unlocked) and took wallets and phones and walked away. Noone thought twice as there were so many people around!
Take care, always lock your car, close the gate behind you and keep an eye open for suspicious activity.
