The Global Positioning System, a constellation of satellites circling the planet, is often my saving grace on car trips. This is my second GPS unit, and it is a Godsend.

I don't get lost easily. That's not a tribute to any navigational skills you might imagine I have, but more of a result of the fact that I don't often leave known routes. Pre-GPS, when I drove any distance, I usually had a road atlas or Google Map directions. These were fine until you got turned around, missed a turn, or were in a town the atlas/directions didn't cover.

Fortunately, with portable GPS receivers programmed intelligently with directions, waypoints, and attractions, it's almost impossible for me to ever get truly lost. And that, my friends, is a good thing.
