@ShiroKuro, What a wonderful experience!
We also have an artist's cooperative in Plymouth, one of my favorite stores. I'm quite susceptible to impulse buying there, though, so I have to be attentive. They don't have a piano, however we have a fantastic thrift shop called "Step Ladders" that has a baby grand in their 'lobby' area. I haven't gotten the nerve yet to play it yet, but I've been thinking about it.
