If you have ever visited The High Line park in Chelsea, you have probably seen a few things. The tasteful plantings and unique aesthetic contours of The High Line itself, for one. The crowds of pretty young NYC things and happy tourists taking the Hudson River views and generally making the park that much more scenic, for another. And over and around it all is something every bit as dramatic, but much easier to miss -- there's West Chelsea itself, growing up and growing into itself and generally making New Yorkers forget that there was ever a time when the words "luxury condominium" and "Tenth Avenue" just plain didn't go together.
