Too many shops?

'The High Street', that catch-all term for the trading places of a town. Now, to me, it suggests as much as anything else a counter to the 'out of town' trading places that have sprung up over the last decade or so. Lots of changes have happened, lots of changes on the way no doubt. Our project is somehow bound up in these changes. Heard this today on the radio, an interesting viewpoint from one 'retail expert'.
