Apologies if you went to my site this morning to see my blog from the bloggers table at PASS Business Analytics Conference.  Turns out a firewall issue blocked me from getting to my site (and many others).  So I wound up tweeting updates at http://twitter.com/jamesserra.  You can review my tweets from today, and then check back tomorrow from 8:00am CST and 9:15am as I will tweet all the goings on, when the presenter will be award-winning economist and Freakonomics author Dr. Steven Levitt.
