Walking is fantastic exercise. But while American suburban sprawl doesn't naturally lend itself to walk-happy travel, $4.00/gallon gas is sparking some to slip on their sneakers to complete nearby errands.

Conveniently, Google Maps recently added a walking directions option to its website. Pop in your to/from and it'll spit out route, mileage and estimated time to walk to your destination.

Cool! According to Google Maps, my neighborhood grocery store is 1.4 miles away and should take 27 minutes to walk there. Ha -- I can walk faster than 3 mph! Maybe Google should add a 'jogging at X-mph' option, too. Now if only Americans could live in European-like villages with fresh, organic food markets scattered on street corners. Nothing wrong with Big Suburban dreaming, right?
