I was at the shop working on one of the trucks today and had my 2 year old son with me (my helper). This police cruiser stops in front of the driveway and puts on a show of lights and sirens for my boy.Well, I got to talking to this officer about the mounting systems they use for laptops in their patrol cars and he calls back to headquarters to ask them where they get them. They purchase them from www.jottodesk.com and the prices seem very reasonable. I just thought I would share this info seeing as I have had a hard time finding these things for myself. And I thought I was going to the BIGHOUSE!!!
