Yes. I think we're probably agreeing on this, that the need is definitely there. The winds of change are there, because IMO was a global agreement and very soon there are going to be the 33 countries, and 35% of the global trade is going to be done by countries that have agreed with this need to deal with ballast water.
We sit and look at our problems. There are exactly the same problems all over the world. Our invasive species are showing up in New Zealand, and they're showing up in the Caspian Sea. We're all dealing with the same thing. Every summer we have 500 ocean-going vessels come into the Great Lakes. So we're saying those 500 that come in have to have ballast water technology. There are tens of thousands of ocean-going vessels around the world, but we have 500 a year that come in and we're telling them to use their logistics software, as they would for the width of our canals and the depth of our harbours, to also make sure their ships have ballast water technology on them if they're going to come into the Great Lakes. It's not hard.
