Unfortunately, the audience was quite small. ASU's Polytechnic Campus is way out east of Phoenix, on the former Williams Air Force Base which ASU purchased and turned into its east campus. It doesn't appear that it has a very large student population yet. I was amused that the streets are named after military figures. To get to the Student Union I drove on a street called Twining, named after General Nathan Twining. Twining is a name well-known to UFO enthusiasts, as his name was used on one of the forged "MJ-12" documents known as the Cutler-Twining memo, and also authored a genuine document that discusses UFOs (and is often misinterpreted by UFO advocates as claiming that crashed saucers have been recovered).
My talk was followed by a talk on Wireless Security by Erik Graham of General Dynamics, which covered threats and defenses for 802.11 and Bluetooth.
