Here’s my top 3:
Supposed to see Franny Drake’s Golden Hind as part of a history trip but the weather was too windy and it wasn’t safe for the coach to cross the Humber Bridge
Some kind of Geography trip to the seaside to study coastal erosion but a car crashed into the coach en route, ambi-copter came, was all pretty serious but no casualties. Got there in the afternoon and just pissed about on the beach for a bit.
Sewage works, literally shit.
What’ve you got chiefs?
