This is a bit of a plea … Alright, it's actually straight up begging, but it's for a really good reason. Colorado's state fish is the greenback cutthroat trout, and there are just 750 little guys left in the wild. They're all in one tiny creek just outside the city of Colorado Springs. Yes, you read that right - there's just 750 of the species left in the wild. This came as a surprise to many people in the last year.
