Query: How did I survive without this thing

I just did my first trip with the Garmin Streetpilot III. It was awesome. I am a very good map reader and can usually look at the map once and memorize the route, but I have fallen in love with this tool. Never again will I worry that I may have missed the road I was supposed to turn on, when in unfamiliar areas. Finding a restaurant or gas station is also a breeze. I will never travel without this again.
