I often wonder as well, Nigel, if the location of the site is a factor.

While I've seen tons of crap left as offerings over the years, I've never actually seen anyone leaving it.

What I mean is, is it more likely to happen in places where the litterer can't be seen, or there aren't a constant stream of people?

I wonder how tolerant people would be if, for example, at Avebury, all of the cack at Swallowhead Spring was left in a "respectful" heap right next to where the Obelisk stood, or "ceremonially" chucked over the Cove stones.

I can't imagine it'd stay there too long.
