While I was in the bed at work at the fire station, it said I was 5 miles away in another town at a house I have never been at. I was talking to my wife, while I was in my own bed at the station, she mentioned the locator and while I was on the phone with her it showed that i went to that same house AND BACK in 4 minutes. Remarkable that I never left the fire station. Please all spouses realize the uncertainties.
