I just googled "Minchinhampton Blueboys" and was surprised to find that so many of the results were about Zara Phillips! She certainly was not to be seen on Blueboys corner, or if she was I missed her. The nearest I got was signing for a packet one day and noticing that she was next on the list!
I've also just looked at a page all about Minchinhampton which claims that it is the least accessible of the Cotswold towns - why then do so many cars and lorries go through it on their way to Stroud?
They don't go down the main street but they do whiz (despite the 40 mph speed limit and the cows) over the common and through the Blue Boys end of Minch.
