Very good points my friend. I have been an EMT on a 911 ambulance in my county for 20 years. We went from having a map book when I started, to now having a laptop running a CAD system in our units now. The CAD works pretty good sine it will route you to the call much like a Garmin. Sometimes the routes are stupid though and will have you go the long way to get somewhere. The good thing about working in the country you were born and raised in is the fact that you know the roads pretty well and cut the corners to get there faster when that happens. Making sure you have your house number in a place where we can read it is good too.
