I don't have any direct connection to Black Blade Publishing any more, so I'm free to be a fanboy. :)
If you're going to be at North Texas, Allan and Jon will be there and have a table like last year, and it's going to be worth checking out. They will have OSRIC books and Monsters of Myth, and will also have Robert Conley's Majestic Wilderlands Campaign (and the shorter Blackmarsh setting as well). I think they will also have copies of Jeff Talanian's excellent Charnel Crypt of the Sightless Serpent, too. The available numbers of books will likely depend on the capacity of Jon's car, since he drives it all to the con.
It's true that you miss part of the Black Blade Publishing experience if you don't order by mail -- Jon Hershberger packages books apparently on the assumption that battle tanks will be driven over them, and you will never see such sturdy packaging. It's built for Ragnarok. Nevertheless, it's really cool to see real new AD&D books lying side by side for sale on a table. Definitely stop by and check it out while you're at the con.
If need be, you can spot Allan at a distance. Look for the tie-dye t-shirt.
