I’ve just returned from a three-week trip exploring Scottish Gardens. My husband and I rented a car at the Aberdeen Airport and set off for our adventure. Rich did all the 852 miles of driving with a right-hand drive and a left-hand 6-speed shifter. Our GPS guide was the calm and reassuring voice of the actress Emma Thompson, and we loved her. But it takes both of us to stay focused on driving down shady tiny “B” roads with one-lane bridges, watching out for horseback riders, cyclists, and huge farm equipment along the way.
