For me, it's the 'Caledonia' phenomenon.
Check out the opening sequence of Monty Hall's show from Applecross on the box on Sunday night.
If you wish you were there and a living breathing part of that country then that would maybe give you the feeling of what it is to be a Scotch-man, or rather a Highlander.
I clearly recall living in London and nearly greetin at the scenery on Monarch of the Glen, I'd never really experienced homesickness until then.
It's always highland phenomena that really get me - the moors, the stags, the mountains, the glens, the slate grey skies and seas, with the odd blue sky day just to show off what it can do when it wants.
Views over Auld reekie can do it too.
Not so keen on the Weegie end of our wee corner of the cosmos right enuff. If Glesga was to become part of England-shire, that would solve all my problems with the bonus that the the OF could then join the EPL, although they'd be more at home somewhere in Oireland apparently. Not to keen on Eberdeen either now that I think about it.
