Good question — I read the book at home, but it did make me an impression on me when I went out on my next solo trip. I’m also not one of the “stick breaks, abandon camp!” type of folks either, but for some reason this book did make me feel a bit less comfortable with solo off-trail travel and its potential consequences.
I’d say it’s a good read wherever, but maybe some extra melatonin or just making sure you have your safety plan dialed in would be sufficient — either PLB or detailed itinerary with a reliable person.
