I'll be there Saturday to help out. Note that Saturday is also Open Data Day (http://opendataday.org/), and AT&T is enthusiastic about supporting it. Dallas isn't formally listed (http://wiki.opendataday.org/2014/City_Events) unless some group wants to take it on? Unfortunately I wasn't able to commit. No matter what, attendees can still contribute to the cause.
