After walking miles and miles through Chicago’s McCormick Place at the 2012 AHR Expo and hitting virtually every HVACR-related booth over a continuous eight hours to the point where I could hardly stand, I welcomed the opportunity on the second day to sit through several programs put on by manufacturers - but I was one of the few. Later in the day, there were only two of us in the room to listen to a couple of very interesting presentations on products that I had missed on my walk the day before.
