Hey coldfeet I was there on the 24th as well, interesting.
Took the train in with my g/f, we walked around for quite a bit. She really enjoyed it, I thought it was pretty neat. I liked how I could "see" the wind blowing through the gates here and there and other places they were still. A few things I enjoyed was that all the money for this project came out of the artists pockets, and the money made off of the books/pictures etc they sold went straight back to the park, not to mention all the tourists it brought (like me). I also appreciated the fact that of the three hours or so I walked around in the Gates, I never saw any graffitti or other sign of vandalism to them. I know the artists have a security detail at night, but 23 miles of Gates are easy targets nonetheless.
However, what is most impressing is Central Park itself. Within moment of walking into the park, it gets quieter, more peaceful. Central Park in itself is an amazing piece of artwork. The city melts away, and you feel like you're in another world, while just a few feet away people glumly hussle around... What a lifesaver for that town. People smile in the park, laugh easily, and are not running from sidewalk to sidewalk. Even the signs are more peacable (This lawn for sleeping, reading, daydreaming, etc...). Its a special place for New York, for sure.
Having said that, thank goodness I don't live in NYC.
