There's a pavement pizza at the bottom of one of the exit stairways from WSU that's literally been there years.Every time I walk up the steps to the WSU there is a big patch of what is clearly old vomit spattered up the wall. Not sure what game it was 'created' in (I'm going for Fulham) but it's going progressively greener and more cultured every time I go past. Makes you wonder how often anyone from facilities actually walks up those steps to check them.
