It took mankind thousands of years to domesticate horses, and even after we had tamed the beasts, many people still relied upon their own two feet to travel where they needed. Armies of men marched thousands of miles to wage war, and many of the greatest explorers had nothing but their legs to take them through uncharted lands. And in the span of just two centuries, mankind, it seems, has forgotten how to walk.
Ok, that last part might be a bit of a stretch. Cities are growing, and many city dwellers walk day in and day out. But many Americans don't really have a choice when it comes to walking. The lack of sidewalks and distance from basic amenities mean cars or buses are the only real choices. If we build more walkable neighborhoods though, will more people start walking?
