R Clayton McKee | Photo Galleries | "Sunday Streets Houston" -- Westheimer

"Sunday Streets" is a Houston project to encourage residents to be more physically active (and interactive.) A section of a major street (Inner Westheimer, here) is closed to automobiles for several hours on Sunday, allowing pedestrians and human-powered vehicles to use the street freely. Shops in the area run special deals and food trucks congregate. The effect is almost block party, but perhaps a bit more commercial.
