$64,000 Question: Sophie & Blackie??

So, today’s $64,000 question: what wnry was Sophie (cat) and Blackie (dog) associated with??
When I did my first visit there, I took a small bag of dog treats. When I pulled up into the parking lot amidst the vines of the Henderlong vnyd, Blackie came racing out to greet me. He took a mouthful of the treats and then slunk off into the vines, feeling guilty as hell for taking treats from a stranger. He later rejoined us in the wnry.
Sophie was there, too. But, as cats are wont to do, totally ignored me.
