Scot Miller owns Sun to Moon Gallery on Keller Springs Road in Carrollton. He's also on the advisory board of Groundwork Dallas, the 2-year-old nonprofit charged with cleaning up parts of southern Dallas -- including, especially, the Great Trinity Forest. And it's all about getting the kids involved. (Groundwork Dallas is, in fact, part of a much larger nationwide program that is supported by the Environmental Protection Agency Brownfields Program and the National Park Service Rivers, Trails and Conservation Assistance Program.) Yesterday, Miller posted to the YouTubes a six-and-a-half-minute film about the project and the Great Trinity Forest, which is worth a look this a.m. --Robert Wilonsky
