Well, I'm back now, and I enjoyed them - As another poster mentioned, the interaction of people with the gates was one of the things I liked. Either with us directly or by just sitting on a bench with a snack and watching others.
There are volunteers that use these long poles with tennis balls on the end to unfurl the fabric if it got flipped up in the wind. We saw them fix one and the crowd that gathered to watch started clapping & cheering when it unfurled. Kind of silly but it gives a good example of the positive energy of all the people there walking around.
And it is cool when a gust of wind comes up while you're looking at a several gates at once. Or when the sun would pop through the clouds and really light up the orange fabric.
Overall, I think I liked it more than I thought I would - I recommend checking it out if you live in the greater NYC area.
On a materials note, the steel beams almost had a plastic feel to them when we knocked on them, like they were coated in plastic or something. Not really sure though...I was going to ask someone but forgot...
