Me, I like history, prehistory and stones and religion strangely enough, though I won't be drawn into Dawkin ;).. the way everything blends into each other. Cope's book about the sacred nature of place as well, gods, mythologies, the ultimate mysterious nature of stones because we can never really know the truth - the fun is in the guessing - I don't take anything too seriously, if a thread is boring I don't read it.....
One thing I would like more of though, is photographs of the landscape round the sites, a larger picture of what is happening.....
