I visited the gates during President's day weekend and found myself more awed by amount of vistors to the park during wintertime than anything else. That isn't to say that I don't think the gates have artistic merit, but personally I found that the engineering and logistics of creating and placing 7500 gates overwhelmed the creative sense of the project.
Today will be the last day before the gates will be taken down. For those of you who missed it, there are many photos at
