In case I hadn't mentioned it before, there is a new Texas gaming con called TexiCon which takes place May 21-23 in Ft. Worth.  Their web site is:

I've sent an email to the guy in charge of Board Games to see about a) the possibility of trying to get a one or two round Diplomacy event scheduled, or b) a teaching game one or two of the days.  I'll let you know.

Either way, take a look at their site and see if you're interested in attending.  We need to support local gaming!
