A Sunday afternoon and just a few minutes after I had scaled the fence and was taking the first few pictures of the earthworks the gate to the site started to open and two guys appeared. There was nothing to do but say 'Hi' and see how things went. It was awkward and I left a couple of minutes later (and went and took pictures elsewhere) but I still feel unsettled. It's no different to the apprehension about being unexpectedly found wearing a dress.
