road bikes

It's the middle of the summer, and I was thinking about taking a bike trip (part of why I need that GPS -- woohoo!) and then I realized I don't have a bike. Man. As road bikes are getting fancier and fancier, I'm not sure I even know where to start. Well, mountain bikes are more off-road, while road bikes are...on-road? There's racing bikes, touring bikes, and utility bikes. Touring bikes are more for heavy loads, and utility bikes are for day-to-day errands. Or so says wikipedia.
