One of the great innovations of the modern age—something even more useful than the beer-can hat—is mapping applications such as MapQuest and Google Maps. Not only can they show you the fastest way to get from A to B (accounting for traffic, construction, one-way streets, and other obstacles), but they can give you alternatives, such as those favoring or avoiding freeways or scenic routes. Some applications will even give you the best routes for traveling on foot, by bicycle, or public transportation.
