Last night out to dinner with friends on Telegraph Ave. Got back to car and noticed a lot more noise driving through the Caldecott Tunnel. Looked over my shoulder and saw the rear seat (passenger side) folded down. I first thought my teens folded it down until I saw the rear quarter window broken. The vandal didn't steal anything. However, in the SF Bay Area this is becoming common practice. Vandal shatters rear quarter glass, reaches in folds down seat to check for valuables in the trunk. I think from now on I might leave the cargo cover up so they can see there is nothing in the trunk without breaking my window. It was a disappointing end to a great evening. However, in the grand scheme of things it was just a broken window that will be replaced.
