Wednesday was International Walk to School Day. Among the 3,784 U.S. schools participating this year was P.S. 197 in East Harlem, where kids were joined on their regular commute by Grover of “Sesame Street” fame, along with other guests. Robin Urban Smith of Streetfilms was there.

Check out the vid for improvements near P.S. 197 that make crossing the street safer, and read about this year’s “We’re Walking Here” program from DOT, which offers schools a $1,000 prize for designing their own pedestrian safety campaign materials.
