Horror stories/lessons learned

[Dparker]

I thought i'd start this thread for the benefit of all. The reason being is that a past olympian Paul Henderson once said " nothing is learned except throught the eyes of disaster" The idea is that we can learn from others( instead of making the same mistakes)- keep calm and carry on! Im just waiting for the track to do what its going to do ! Please add your confessions, yeah we know you were smarter than that!
