Well not so much a breakdown as a non start. The ignition switch ceased to function. Mechanic arrived and gamely tried to bypass but the wheel being in locked position wouldn't allow this so piggy back time. Lack of mobile signal and busy RAC meant us going only as far as Lochcarron or facing a carry to Inverness and then half way to Edinburgh and another swop of carrier likely arriving well into tomorrow. Opted for the night in the village. Happily good friends are currently doing up a house there and put us up. Also well fed and watered (the whisky at least), and Margaret got to see her chum Tristan.
So thanks to Sheila and Jim we had a convivial evening.
