I have also noticed that the main bulk of loons seem to come from the British Isles! No surprises there then! In the end I met some nice guys and gals and we often sat around laughing at all the past nutters we had met when first arriving.

Reading what you have posted, as per the above, makes me think of all the British loons I've run into here in mainland China over the years, a motley crew indeed!
Actually, we could do with more Australians over here. They know how to party and run after the local females. I think having a good time abroad is of paramount importance, and the Aussie blokes I've come across certainly do that!
