But I have a good security tip.
If you live in a town whose crime rate is really going up, fast, like my town, where people will are getting dangerously bolder than ever before, don't drive around with navigator or Ulyses speedometer lit up on your dash, just screaming, "grab me".
I didn't realize the potential danger I could have been putting me and my phone in until my buddy brought it to my attention that I was being pretty stupid "advertising" my nice phone on my dash everywhere I went.
I guess were back to the common sense thing, my own of which I question.
