I just thought I would let everyone know about what happened Sat at Mountain Quarry.
I was climbing there with a couple of mates who parked their car outside the gate which subsequently got broken into. A rock was thrown through the drivers window and a mobile phone was stolen off the seat as well as two bags of old clothes (???) from the boot. Stereo was left intact, probably because the alarm was going off and it would have taken too long to remove.
As for the gate, there were commercial operators running an adventure course there and someone must have left the gate open, because when I got there it was unlocked. When I went to close it when I left the metal bar that the padlock clips onto was missing, so it is currently impossible to lock.
