I did notice the one on roof had no screws holding it down. I never really thought of the fact that someone could have set it there and forgot about it. Because "who does something like that?" says the guy who put his cell phone on the rear bumper and drove off. I went looking for the phone a hour later. I found it but only after it had been ran over. Thank goodness for Otter Box Cases (and just maybe the Toyota Prius that ran it over certainly was not a one ton dually).
