I was reading Brian's concerns about security. I don't think this would work so well with being in school all day, but wanted to say that wherever possible, I take my dog with and leave her in the truck. She has a dish of water and when she lays down gets shade. I have her tied in with a horse trailer tie that is attached to the rear seat flip handle (the one in the middle, at the floor). I figure it will be some form of intimidation at least. Too bad she is a Golden and always wagging her tail. Oh - the trailer tie makes it so that she can't possibly jump over the bed sides and strangle herself or anything. She can stand or lie down. She loves to go for rides. I bought a cd player for the truck in December and I don't know what we were thinking, but the faceplate is not removable. Have a great weekend!
