Evidence of revelry

Tell-tale signs of the end of the exams for various students around town. Not all as subtle as this (I mean, who looks in drains on the off-chance there's something worth photographing in there? I'm starting to worry about myself.)

Anyway, another example of the weird rituals the university bods entertain in this town. Markedly different from my own experiences in a somewhat less grandiose establishment oop north...
