That's the only time I've ever used one of those GPS guide systems--when my wife and I were on vacation. Otherwise I prefer to look up the directions on Google maps when I'm at home, especially if I'm trying to find a residence or business I've never before been to because that "street view" function lets me see what the building looks like. I submit slurring Joe Namath as evidence that football helmets as protection devices aren't worth the dynamite it would take to blow them up. Sure, they're fine if the wearer's head only hits the Astroturf once every 1,000 games or so, but that's rarely the case and that brain sloshing around within it's bony housing is still taking on damage each time, helmet or not. I've never listened to an audio book either. If I want someone else to tell me the story I'll watch the movie.
