About 3 hours on the drive for our family vacation, we stopped to grab some lunch. There was a Best Buy right there and I decided to wander in and pick myself up a GPS system since we'd be wandering.
I hadn't used one much before, but now I wonder how I ever traveled without one. This just takes so much stress out of traveling. Really, the greatest invention since they started slicing bread.
You get to pick the voice that talks to you. I picked one called "Susan", which is now what we call the thing. My wife seems a little jealous. Perhaps because when "Susan" tells me which way to go, she does so in a polite nice voice instead of irritated nasty voice my wife can sometimes take when she's navigating. That, and "Susan" hasn't lead us astray yet. I think my wife feels replaced.
Man, it's cool to say goodbye to mapquest printout's and to never worry about finding our way back. This thing is SA-WEET!
