Scotland was for many years my home; I lived mostly in the Highlands and Edinburgh, and in Glasgow (where, incidentally, I have never eaten a bad meal, and have frequently eaten world class food) every January for Celtic Connections.
There are many different Scotlands. The Highlands are not the same as the Borders, the islands are definitely different from the mainland, especially the Northern Isles ( Orkney and even more so Shetland), the cities are different from the rural areas.
Nowhere have I ever seen anything remotely resembling The Wicker Man - except at Edinburgh's Beltane Festival. https://en.wikipedia.org/wiki/Beltane_Fire_Festival
