Skeates book has a lot of excellent management of sites examples ref ethical and political of USA sites. Especially in the first half of his book. It's on the reading list for today. I especially thought his Hawaii examples are stupendous. I am jealous of those who are from the USA as Being English I can't use these examples. I do think his narrative is slightly biased towards western hegemony ideas and concepts though.
By the way there is a conference soon at UCl on the destructions at Palmyra an appalling tradegy.
