From what mailing list?

Here's another poser. How is it that I've been sent a free issue of Garden & Gun magazine? It's true that I'm interested in reading it,although probably not in subscribing to it, no matter how great the deal. I'll read any magazine, practically, and I'll read just about anything that can be read, at least once. But how was I identified as a subscription prospect for this very handsome and glossy magazine? The tag is "21st century southern America." It's perfect-bound, not saddle-stitched. I guess I'm flattered to be in the same demographic as Road Bike Rider and Garden & Gun. Or should I be? Here's the current G&G table of contents.
