Are we talking original purpose or modern use here (or both)?
Strangely, the use of the terms 'rave' and 'pig' in such close proximity made me have to read that a couple of times to get the meaning
Do henges have a modern purpose?!?!?! What would that be?
I'm thinking original use.
I dunno if there IS any relevance to it, but my friend just mentioned it as a matter of course, so I presumed he had some grounding to it!
We'll see, eh? :o)
