 That's fascinating to me. It really is. So what are the threats to these things? I didn't know that a third of the nation's GDP is shipped on the inland waterways. That's a phenomenal number. That's a big, big number. What is needed on most of these locks and dams? Is it, you know, is it they need to be destroyed and rebuilt? Is it that they need ongoing maintenance that can't happen? Tell me what the exact threat is to these things.
