For all fans of Heath Robinson, here is a picture of the lashed together roof strut that nearly fell down in the ceilidh tent. At Shrewsbury a large length of metal fell onto the dance floor. I have a photo somewhere that is about 20 years old of a roofing slate that fell onto the roof of a Volvo estate car at just the right angle and went clean through it - knife through butter. Things dropping off roofs are bad news. Two marquee failures in one weekend is disturbing - some fatigue testing and redesign needed maybe? http://www.seered.co.uk/140_4064_closeup.jpg
