The Macnab Challenge has its roots in a novel from the 1920s. Fictional Scotsman John Macnab was in a life crisis and was looking for an unusual challenge. Most of his hunting activities until then had been of the illegal kind. One day, he challenged the owner of a large estate with the statement that he would soon remove the quarry of a single hunting day and return it to the estate house undetected.
Although this boastful statement probably involved plenty of whisky, John Macnab kept his promise and soon delivered a stag and a brace of grouse to the estate owner’s door. He completed this impressive feat with a salmon that he had caught in the nearby river, with a fly he had made from deer hair.
The story of John Macnab remains popular to this day. It has encouraged many hunters to copy his efforts – legally this time – and accept the challenge of shooting a stag and a brace of grouse (two birds) and of also successfully fly fishing for a salmon.
