Have you ever seen this series on PBS? If not, you should.

I remember watching some of this and missed some of it unfortunately. But well worth watching the whole thing. Good history. Good thing we had some folks who decided to save some of our forest, streams, etc.

Ken Burns has consistently produced the best historical documentaries I've ever seen. Haven't seen this one yet, but I'm sure it's on a par with his others. Rick

Watch for it on PBS, or maybe some day you will see it when it does not cost so much. Definitely worth watching.

Oh cool. Gonna watch & wait for the DVD price to drop a bit though.
