In eastern NC, I'm far away from any mill that has CC, to my knowledge.
Can anyone recommend a reputable online source? CurlyMaple.com,
perhaps?

I have bought curly cherry from
http://www.westpennhardwoods.com/static/index.htm
But I bought it in person. I don't know if I would buy wood like that
online; I mean the boards are really individuals rather than a commodity.
