Yesterday we took a couple of hours off for a visit to the "Highline", a park, or something like a park, that opened a couple of years ago in Chelsea. It is built on the remnant of an elevated train platform that runs through some twenty or so city blocks on the lower West Side of New York.
It's a pleasant walk, much quieter than the street or than Riverside Park South, and there are interesting industrial views to be had in various directions.
