And then on top of that one, actually a month ago, a month earlier, I had gone to what's called the Logistics and Accuracy, I'm not sure I'm saying the name right, but it was basically a session where the public, anybody, could go and watch them check their machines. These technicians was in this big old room, literally would check each machine one by one. You, as an observer, stands behind these ropes and you watch them.
