Arizona's Payson Roundup newspaper has a great write-up by Christy Powers on ClickerExpo Tucson, with a picture of Karen Pryor and Higgins, a beautiful black dog who helped with some live demonstrations. From the article:
Imagine attending a three-day conference with 300-plus people and 100 or so dogs. Clicker Expo was an exceptional opportunity. I have attended many dog training seminars with top trainers, but this was far above and beyond those experiences.
