 That's true. But, again, we've made a lot of progress, too, and I don't want to lose sight of that. A lot of people put a lot of work in over a lot of years, and we've come a long way. For example, we used to have raw sewage flowing into the river with combined sewer overflows throughout the entire year, and that's been reduced dramatically. It's cost $1.4 billion to deal with our combined sewer overflows, but we have made progress. Historically, we used our rivers basically as dumping grounds. We built our cities along them because they were great transportation corridors.
