yeah, cheers flywaver, interesting stuff.
Some of these will be spurious, some misid'd, but some will be genuine - the ones at dobcross and wessenden moor, near me, seem so and they tie in with a sighting I know of.
In the countryside centre, a chap talked to me about a big black cat that scared the s... out of his dog - the dog knew it was there before it was spotted and ran home out of control. Very plausible detail -that sort of experience just calls the doubters into question I think.
Elements of realistic needed yes, but also a few quite likelies, so keep a look out.

Cheers
