One summers afternoon I took the kids swimming in the Mersey but the sight of a bloated dead cow floating past made us head for shore. It must have gone overboard when being unloaded for slaughter at Birkenhead.
When we reached land we found we were covered in tiny black worms that flicked their tails at us. (Screams all round.)
Later we arrived home to hear the announcer on 'Look North' telling us that injections were required before entering that particular river.
