Edinburgh comes in herds of stags and flocks of hens

Stags drunkenly stumble up and down the ravines from pub to pub with football (soccer) transmissions and dreams that some girl might find there combined alcohol fumes attractive.
Hens flock together in the back of buses and drink fifths of vodka from plastic-bag wrapped bottles, moan about loss of chewing gum packets, mistake a gay couple for possible prey for pointless flirtation by claiming one is, or looks, like Harry Potter. The two Scots behind the couple are jealous of the attention and offer one of the hens some gum.
Covens of mixed sex college kids come around the corner with determination to find the next pub offering student discounts (2 pints for one, or such) on inebriating substances.
The castle is illuminated and from the garden in the ravine behind it BBC is broadcasting live some version of "whoever wants to be a millionaire must laugh at anything".
The buses have usually no back doors.
The food is in general good.
And watching the natives is a source of infinite entertainment!
Pictures later.
