" The world's first sidewalks appeared around 2000 B.C. in what is now Turkey. But it was in Paris - where there are at least as many styles of wandering (flanerie, derive, errance) as there are the customary cheek kisses (la bise) - that the sidewalk became an avenue for pleasure. No need to follow the 1920s-style red METRO sign underground, or climb into the taxi with 'Parisien' on its rooftop light. From the sidewalk, the best of the city can be had for free. "
