In a jam

Trust a radio critic, she who is paid to listen, not to rely on the wireless set in her car for information when stuck on a highland road miles from anywhere in a jam that stretches far into the horizon in both directions. But when a forest fire closed the road we were travelling on back across the mountains I realised I hadn’t a clue how to retune our southbound radio from the preset buttons and so couldn’t find the local station, Moray Firth Radio.
