New York has unveiled High Line Part 2. The NY Daily News writes about the lawn panel and Fox News gives an overview of the High Line's "secrets". National Geographic just ran a feature on Part 1.
There are already photo galleries of Part 2 online from:
The Seattle Post-Intelligencer
Garden Design Magazine
And the New York Times has given the High Line its own Topic Page. Presumably their big splash on Part 2 will appear there when it is ready.
