Out of road

Couldn't resist taking this picture. We had arrived at Cairnryan, Scotland and were waiting in the queue to board the evening ferry to Belfast. The satnav was still on and I noticed that we were out of road.
Now there's a metaphor - out of road.
Sometimes when we run out of road, reach the edge, it can feel as if there's nowhere to go but back. This road, the Belfast way, continues on the other side of the North Channel and heads for home.
Next time I feel like I've reached the end of the road, I'll be checking for a bridge, tunnel or ferry.
With or without a satnav.
