An Idea Into Action - Congressman Mark Green

"As an avid fly fisherman and outdoorsman, I care deeply about our environment. Unfortunately today, some of the extreme proposals out there have forced conservatives out of the discussion when we should very much be in it. I came up with this idea as an easy way for everyday Tennesseans from both sides of the aisle to come together and take a small first step toward protecting our environment, and beautifying our interchanges too. Because of House Ethics rules, I can't be a part of this project directly, but I am honored that this team has launched my idea, the Green Interchange, and I can't wait to see the impact they make".
