Yeah, I was probably just seeng things (the way people see the face of Elvis on a cheese and onion crisp sort of scenario) - the more I looked, the less certain I was to be honest.
It was lovely anyway - a couple of middle aged couples (who seemed to be into this stuff) came and went, plus a noisy family with a dog .... the dog seemed more interested than the kids as he waited in hope for a gigantic rabbit to emerge but had to make do with Mrs Wiggy. Once they'd gone we had the place to ourselves. Fantastic.
