I did! After two years of sending out manuscripts I finally got not a rejection letter but a “we’re buying your story” letter!!!
It’s the spring 2006 issue of Subterranean Magazine.

Scrolling down one finds:
That “tales of a Barsoom-esque Mars” is mine!!! My story will appear in print for other people to read, and I’m getting paid for it!! Woohoo!
Now I just need to sell another one. I hope it doesn’t take another two years.
So that would make you a professional writer.
Congratulations.
Today sir, you ROCK!
Congrats!

Thanks, everybody!! I’m still bouncing. I let out a big “Oh, my God!” when I realized it wasn’t another rejection.
Chuck, I have to admit I’ve been thinking that it’s a nice first sale. I mean, I’d be thrilled to have sold anywhere, but this is awfully cool.
Rock on.
