I agree with Clatty about sailing close to the wind with addresses. I know it's in a good cause so to speak - i.e., punter's safety but ...
Anyway my own tuppence worth - I know from a girl who stays near the Mirage that there are two guys who hang about the phone box across form the Mirage - that is apparently where they receive/distribute certain substances. Apparently they are - 'otherwise' - harmless and nothing to do with any WG. All the locals seem to know them.
But the first time I saw them I got the same feeling as Paulc. Being from a rough part of a big city I brazened it out and they just ingored me, as I walked past never even looked at me. If they're dealing 'stuff', I don't suppose they're looking for trouble. Don't know if it's the same two but it seems an incredible co-incidence.
