GPS systems in the car are a GREAT idea. I used to have one... but without it I always seem to get lost!! Do you prefer built-in or portable GPS devices?
I have a portable garmin GPS that I just love. We have two cars, so the portable is easily moved from one car to the next. In addition to that I just bought that riding lawn mower so I can even put it on there (LOL). I also turned on the female British accent on my garmin - sometimes I think she gets frustrated with me when I take a short cut I know - she keeps coming on and saying recalculating:) I will have to write a review on her pretty soon cause she is wonderful (Hope my bride of 40 years doesn't read this):)
