In reply to malk:
>felt was prob too young/mellow to tut at you when he saw you up there violating the sacred stones..
I wasn't violating, I was channeling the power of Avalon <cough>
I went there a few time in the summer for the solstice, and it was like entering a war zone. One year, we drove down some B road and there were 50+ riot vans all full of bored police with riot gear. We ended up going cross country, wading rivers, hugging hedge rows and avoiding helicopters with search lights. It was awesome. We got as far as Wood Henge before being spotted and turned back.
At the winter solstice, the police officers (both of them), sit in their car drinking tea, as it's so cold. No trouble and a really good vibe.
