Heat has been in rather short supply recently and while I’m determined not to complain about it, the memory of it, given it’s been so long ago, needed to be refreshed. Remember T-shirts? Remember the ability to go outside without sweaters, coats, scarves and hats? Remember beer gardens? Anyway, here’s Berwick-upon-Tweed on a glorious spring/summer morning about three years ago – the kind of morning when there is a hum in the air…The imperceptible sound of stone, grass and metal heating up as the sun rises.
