The starting point for access to the path up the mountain was under a door of a Glasgow museum. From here you accessed a tunnel. This eventually emerged in the open air on a steep mountain track.

I had forgotten my coat. So, while TPR man-handled my mother up the slope, I reversed the route back down to the museum.

Annoyingly, I took a wrong turn in the tunnel. After squeezing back under the door, I found myself in an unfamiliar exhibition room in the ‘wrong’ museum.

I would be stuck here forever. Meanwhile poor TPR would be stranded up the mountain with my mother.
