Millennium Con XXI is approaching in November in Round Rock TX (just up the road from SJG)! I don't usually see much SJ official presence there, but it might be interesting to run an event at the show, as it's usually densely attended for the size.
I usually run games at least two of the three days. Might be fun and interesting to do a Cardboard heroes/Melee/Wizard Dungeon Crawl. Lots of attendees are of the right age bracket to remember TFT very fondly (And in many instances Melee/Wizard was the "gateway drug" to get people involved with Gaming in general.
