"Oh Shit" moments...

my son had an "oh shit" moment 2 weeks after starting uni. Got front wheel caught in tram lines but somehow buggered the back wheel! I felt guilty though because I was meaning to warn him about tram lines (in Nottingham) but forgot.

Seems like most who've ridden in Nottingham have been taken down by the tram lines, I've had my back wheel stuck once but managed to hop it out. It's all about hitting them at right angles.
