Great description! I'd love to see them, but I don't think I'll be able to get up there.
I saw the Running Fence (in fact, I used to drive by it on a regular basis) many a long year ago. I scoffed at it at first, but the wonderful thing was that it really did make you look at the hills in a way you normally didn't bother to do. I think a lot of Christo's art is simply that he puts something in place that makes you see other things that were there all along - but that you never noticed.
This could be a shape, a line, a color. And somehow you've walked by it every day without noticing it, until suddenly...
I couldn't see the photos, btw. Did you post them? Thanks!
And I don't regret it for an instant.
Got some help and got three images up. Have many, many more; it's so hard to choose.
