Perth is the one city to which anyone living on mainland Scotland can travel there and back in one day by public transport with time enough in the middle of the day to attend a conference or a forum.
(I find that Perth is technically no longer a city, because pesky people in the 1990s decided that some cities in Scotland didn’t merit the word “city” even if they’d been referred to as cities since time out of mind. Bah, humbug.)
So although I’d been there several times before, I’d never really spent time there. It was a good place to go for a short break.
