many years ago I worked with a guy who had a caravan at stonehaven. when he learned that I raced pigeons he told me a story about one summer morning when he was lying in bed he could hear something hitting his caravan roof, on going outside he saw racing pigeons running around the site most of them with broken wings and a local jack Russell ragging them. he then noticed that the carnage was caused because the transporter had released them in the line of overhead wires, so when you loss a favourite maybe it too, was a front runner trying to weave thro.wires at liberation caused by human error.
