Hi Bucky,
We've not spoken before that I recall.
I agree with your suggestion of a "site under threat" banner.
Also, I'm intrigued by your mention of the Native American sites.
I'm trying to get my head round some of them, I'm a new host to a forum caled Native Earthworks Preservation (http://www.care2.com/c2c/group/NEP) anytime you fancy popping across to discuss any of the sites there I'd really appreciate a bit of education. When did prehistory end in the states?
