Have you ever been out on the Missouri River? If so, you know it is big, wide, and muddy. There's also litter in the river. Now, there's a lot less litter thanks to the work of Missouri River Relief. On this week's Thinking Out Loud, Trevor Harris talked with Melanie Cheney about why a cleaner Missouri River matters (Think drinking water.) Also, hear music from Violet Vonder Haar, who will be performing this Saturday's Boonville River Festival.
