I really like the original book. The NPS publication is also very good but a bit drier as it follows his journal enties to the letter. Apparently the NPS is working on another edtion covering a different time span.
"One Man's Wildeness" only covers Dick's first 18 months....some of the most interesting times as the cabin was being built and other discoveries taking place. The NPS publication covers a series of years where a major effort was underway turning Lake Clark into a national park. Dick must have almost felt like an air traffic controller some days with the number of visits etc to his quiet lake.
I find the DVD to be as interesting every time I view it as the first time I saw it.
A few years back there were quite a few people peddling the book for huge sums....don't pay over the cover price, it will be out again I am sure.
The NPS publication might be out of print...but the download is free....not easy to read but free. They put this out in large format paper and it is a nice to have, but the original book is the best of the lot in my view (at least to date).
I have a couple of reviews over at JM's should anyone care....
