Better yet. Does it really matter whether or not it IS "art"? It won't vanish into the ether if it isn't art...and I bet Christo would have created it anyway! And the responses would be pretty much the same! I love Christo's running fence more than his other work and I really don't care whether it is art. IMO this question, in a free country and a free market, is a waste of time. There will never be an exact definition of art that satisfies everyone as long as our country is free...Apparently this freaks some people out.
I spent several hours in the Park today, along with hundreds of thousands of other visitors. I was impressed.
