This one of the less important reasons I don't yet own a GPS--the screen is too small and difficult to orient to the real world. But I like the technology, and if I get a chance to so some homework first I'll use Google Maps to find a route and either print it out or trace it onto a paper map. Or find a bike shop or someone on a bike and ask. Who knows--maybe you'll get a personal tour guide, a new friend, and maybe even an offer of a place to stay. All have happened to me.
