Well, I must admit I was in high dudgeon upon coming across this article. It was absurd in the extreme that the artist, Michael Grab, was told he would be arrested for continuing to make stacked river stone sculptures... My thinking was "WHY?!". He has been making these for SEVEN years, much to the enjoyment of the residents of Boulder.
The upside though, is that an outpouring of support for Michael Grab brought about a rapid change in attitude of those who mandated such an absurd law. He was told that he could continue, unimpeded, to create his beautiful sculptures, which are part of the natural beauty of the environs they grace.
