I'm old enough to remember going over The Struie and round to Bonar Bridge, before the 'new' bridge was built! In fact, IIRC, it was still single track then.
Such a gorgeous part of the world.
My A-road journey today excelled itself. Average speed approx 2 mph
Temp FOUR WAY traffic lights in the very middle of the busy town I was heading towards. Took 30 mins to do the 4 miles. Coming home the numpty in front was doing 36-40 mph in the well marked 50mph zone. I really do want to understand why this road induces such 'steady' driving
