Sam,
It's a 3-day conference/training experience that Adobe puts on. They have 39 instructors gurus and you can choose from a wide variety of classes throughout the day. It a great experience. I'm in Vermont so it's a bit closer for me than you. But they host other conferences too! I have a real good friend who is an instructor, Jack Davis, so I get a chance visit with him too!
