The Bronx borough president recently annouced that car-free Sundays might return to one of America’s most elegant boulevards, Grand Concourse, soon.

Sunday street closures are a great way to have an “everyday festival,” draw people outside to spend some extra dough in the neighborhood, and plant the seed for future traffic calming. (If it can be this nice once a week, why not all week?) Memorial Drive in Cambridge and the park drives inside Golden Gate Park, Central Park, and Prospect Park are examples of weekend street closures. Why not, say, Grant Park?
