You mentioned during your testimony that you've had pretty remarkable success over the years with some of the efforts you've made to replace water lines, based on the research we've heard so much about.
First of all, congratulations on the effort. However, have you identified factors that make it more likely for a private homeowner to take up the offer when you guys say, “We're going to test it for free, and if you replace yours, we'll replace ours”? What factors are motivating them to take that offer up?
