I've been wanting to post this for ages but kept second-guessing myself. Figure it's time. This happened to my mate and me when we were teenagers, summer of '98, on the North Yorkshire moors near Helmsley.
We were cycling to a mates house around 6:30 PM, still broad daylight, when we saw something large moving through the bracken about 30 metres away. At first I thought it was a sheep or a goat that had got loose, but the shape was wrong. Really wrong. It was definitely feline - you could see the movement of the shoulders and the way it crouched. Tawny gold colour. We stopped dead and it looked right at us. Just stared. This lasted maybe 5 seconds, then it bounded away into the deeper bracken.
Details: Clear weather, good visibility, both of us completely sober (it was 1998, we were 15), no cameras on us unfortunately. I've never seen anything like it before or since. My mate still won't talk about it. He reckons it was just a large dog but I know what we saw.
Anyone else had similar experiences in Yorkshire?
