As the hiker neared me, I recognised an eager exhaustion in him. "I did it," he said. "My first Munro," referencing the 282 mountains across Scotland whose peaks lie above 3,000ft. With the carpark in sight, he was eager to get off the mountain. "I'm glad it's over," he said. His shellshocked-looking springer spaniel followed after him, barely stopping to sniff my boot.
