 Yeah, we're certainly sympathetic and understand that no one wants to pay higher costs of anything. But we also know that registration fees have not been increased since 2004. And certainly we know costs have gone up, especially construction costs has nearly doubled during that time. And so one of the things that we're trying to do to make it a little easier for customers, something new they'll see, is they are offered a one-year registration as an option. If they don't want to pay the two-year fee, they can do that one year. And as you said, it is based on weight.
