It was a pointless game in the main but there was a vaguely serious side to it. I wondered if a street's name had any bearing on it's status - i.e. could you in some way work out the expensive ones from street name alone - and the answer is quite definitely, no.
It came to me from Only Fools and Horses, where the "millionaire's row" was called King's Avenue which does indeed suggest a grand residential street indeed.
