From our experience, the legislation itself, without any kind of enforcement, has a positive effect. With enforcement, there's even more of an effect.
We have a public line that we get inquiries on, and there is some degree of importance given to those issues that have legislation attached to them. So it's not an either/or. Education is absolutely necessary, but it's not the entire picture. The legislation is important to give an indication as to the importance of an issue and in and of itself is effective, but the enforcement takes that level even higher.
