I live in Anthem and over the years I have heard many a tall tale told about Anthem, but that one takes the cake. I can assure you that it was not builton Indian burial grounds. Anthem is a fantastic community. Unfortunately it seems to bring about a lot of resentment from fellow Valley residents. I don't know if it's jealousy or what. But for those of us who live in Anthem we love it. If you want to learn more about the community visit my blog at http://www.allaboutanthem.wordpress.com
What I heard was that they had to purchase water rights from the Indians because the ground water had a high level of arsenic in it (and was thus unusable). New developments are required to have proof of a 50 year water supply.
