Maria Taylor (Saddle Creek) recently had her van broken into in San Francisco and had a lot of equipment, merch and personal items stolen. Please check the replies for a list of the equipment and more details.
Bands really need to take care of their shit. Guess what, people of low moral fiber know that a van and a trailer usually means lots of expensive gadgets. There are steps that can be taken to protect your stuff and they are well worth it considering the risk you take without them. When you stay in a hotel, have someone sleep in the van. When you are gonna be away from your van for an extended period of time, put your laptops/ipods/gps in the trailer or bring them with you. A window is very easy to break and alarms are virtually worhtless nowadays. Get a tirelock for your trailer, buy those badass master locks that can only be taken off with a circular saw.
Getting your shit jacked sucks, but leaving it in the van where all someone has to do is break a window to get in is not taking care of it.
Man what a bummer, I wish I had the means to replace all your gear. It must be terrible to be out there trying to change the world, and then having to navigate bumps in the road like this. Keep your head high! What doesn't kill you makes you stronger, eh?
