I feel a bit guilty when I read stuff like Tombo's fieldnote here....

... but I still have the same underlying perception that I mentioned before, that although there may well be a few specific local cases where there are strong grounds for speculating or believing, the principle has been claimed to extend to a large number of other locations where, purely to my eyes, there's very little justification and it all looks a bit thin.

Either I'm right or wrong, but it's hard to form a view on the nature of ritual landscapes without resolving the issue.
