I do not have GS services but I do have ACSC(AAA) and while stranded due to a very weak battery out in the desert, we called ACSC and someone somewhere said help was on the way. To make it easier to state, they never found us, the dispatcher wouldn't take Long. & Lat. coordinates and would not have the service truck operator call us.
She told the DW that was unnecessary as he was a local and could find us from the street address. He was from a town 25 or 30 miles away and didn't know where the heck we were.
By the way, we had recorded our route in our GPS and had exact street names and distances from the highway to the kids cabin. And we knew landmarks to tell the truck operator about where there were no street name signs.
The address is for a one room cabin on five acres about four miles from a paved road and six miles from any town. There are no street name signs and our Garmin, logically I might add, doesn't know from squat about the Lucerne Valley Quadrangle and the real routes that are available. Many of the roads on the USGS quad maps are no longer there and some never did connect to other roads that are on the maps.
