Look Fitz - how can I say this any clearer?

I am not making any assertions.

I am NOT saying that henges ARE corrals. I am simply asking why we think that they are for ritual purposes and suggesting that they may not all have the same purpose. I have merely raised the possibiliity that some henges MAY have non ritual use such as stock pens. I concede the point made by FW and Nigel that lack of entrance alignment conformity does not prove non ritual use

At a later date, I shall search the literature and see what support I can muster for opinions on non-ritual useage of henges. Its all too easy to explain away everything that we don't understand by saying "RITUAL"
