Sometimes phone GPS acts up. In one occasion when I was driving down the highway it showed consistently I was half mile east of it, like I was floating over residential area parallel to the highway.
Agreed. DS and DD both had their cell phone GPS fail at the same time during a family trip outside of Ottawa last year. They were on 2 different major carriers, which added to the mystery. Thankfully we weren't in a situation where it really mattered. That incident reafg8rmed my faith in carrying a paper map and compass.
