Hi just a thought are these tools in a locked up area ,are they breaking in ? you know you get this in the UK as well I had loads of tools stolen from my garage a few years ago, and more recently they broke into my car parked up at the top of Borrowdale in the Lake District and totaly wiped me out tent,boots ,rucksac the lot,and yet I have been into the Pyrenees and have often left my rucksac at the base of a mountain ,left tent up etc .. and nothing moved.
You get scum everywere,
A friend went to Machu Pichu the other year and was sitting down taking some photos whilst chatting to a couple of locals ,the next thing he knew they put a knife to him and asked for the camera etc.. but left him with his Passport  even bandits have some Morals ? >:(
