CAST - the Conference for the Advancement of Science Teaching - is the annual conference put on by the Science Teachers Association of Texas (STAT).  CAST is the largest state science conference in the nation, typically 6000-7000 attendees participate each year.
With that large of a conference, it is always worth my time to attend.
This year was no exception.
