Ok, just when you thought you'd heard every last implausible story, then someone tops it...
The goat ate the key to the quad bike.
Yes, I went to go on another poo-sucking mission this morning after feeding the horses... and couldn't find the key (it lives in the bike, in the shed). I was convinced I must have taken it out, and actually drove home to check my pockets. It was only having failed there, and every other place I looked... that I went back to the bike and noticed... the plastic surround to the lock down among the goat-poo. A little chewed and battered, but recognizable.
So I did it with the wheelbarrow and pooper-scooper. two and a half heaped-high loads. Have strapped collanders to goats bum. Am contemplating running a powerful magnet down goats (after I have waved it over droppings) and trying a little keyhole surgery.
