I enjoyed the scenery, but on the whole was disappointed. It wasn't clear what the focus was supposed to be...scenery? people? preservation? critters?
Seems that presenting it in a one hour show (including commercials, of course), severely limited their ability to have a cohesive theme and give any kind of depth to the program. That's a long trail and there's a whole lot that wasn't touched at all, or only just briefly (like Vermont, PA, MA, NC, Tennessee).
I was interested to learn of the acid rain problems down south. I knew that there were air quality issues in the smokies, but hadn't heard about the acid rain.
