Are any stores in the D/FW area hosting Sullust events. I asked at Madness last week, and the person I talked to didn't know yet. Any other stores running something next weekend?

On my phone at work so it may ne hard to look them all up for you. But common ground games is doing one Oct 3rd. Texas Toy Soldier is October 4th. Call stores to confirm but I belive those were the dates.

That info is correct for Texas Toy Soldier; you can find the details here, as well as info on the new Armada and X-wing leagues at TTS:
