Fab feedback guys. Lawrence, loved you Total stranger experience - I get that sort of response as a biker, people from all walks of life, of all ages just communicate over a common interest. I guess there are just more bikers than pipe smokers.
I think the Collin's & anotherspace's uni/collage campus probably provides a huge amount of tolerance for the unexpected.
I agree Holms almost certainly would have partaken of a little opium though - and Dr Watson was clearly a smack head.
I also wonder how much the cultural divide of the USA vs the UK makes a difference to the reception we get. My experience is that people in the USA have a much more accepting attitude to self expression (this is a sweeping generalisation - Texas is not the same as New England, I know). But Americans tend to be less judgemental of people's right to be themselves, if they are thin or fat, a pensioner on roller blades is applauded where they would be scorned here as a lunatic. Unless, of course they are from aristocracy, in which case it's just eccentric!.
Perhaps I am eccentric, without the blue blood!
