I'll preface this by saying I'm doing my best to keep this out of the cave. So, I won't get into the specific stuff he says...
So the thesis of the book is really that we should appreciate nature more which includes national parks and farming practices. The book has three parts: 1) a guided hike he did with his friends in Yellowstone, 2) a sustainable farm in Europe that he frequently visits and 3) his airstream trip he did with his wife during the pandemic.
His stuff about caring for nature, sustainable farming, his family, etc are all great stuff and he is a humorous writer. (There's even an Iowa State shoutout!) But he takes these very hard turns into political topics out of nowhere. (He's a progressive liberal.) So, at one moment you'll be reading about this great hike he did in Yellowstone, then the next page is a long rant about supreme court hearings, or Jan 6, etc etc.
I even agreed with some of the thoughts he posited. However, I did NOT pick that book up to read more political opinions. I can get plenty of that crap just walking down the street.
It was just a let down from that regard. An otherwise good book ruined by injecting topics that I was trying to avoid in the first place.
