Camel Farm Break-ins

Went for a ride yesterday ~5pm at the Camel Farm, as I got there a bunch of guys in ~4 cars had finished their ride only to find 2 of their cars had been broken into.

Both had front (passenger?) windows smashed, and i think they got away with 1 wallet, but also took one guys backpack with cycling clothes etc.

As usual, they seem to leave things that can be traced (phones, watches, etc), and just go for cash.

I know this place is usually pretty safe, so I'm pretty pissed about it, especially since I'm there a bit.

I think the general rules apply... DON'T LEAVE ANYTHING OF VALUE IN YOUR CAR.
Take it with or leave it at home. They only come back because they keep getting stuff.
