What is Alex Honnold's reading? My book!

Alex Honnold

In a recent Outside Magazine article, Alex Honnold, the free solo climber, was asked about his current reading list. I was so excited to learn that he's reading Off Grid Solar! Apparently he wants to add solar to his van and he got his hands on my book! 

My wife and I just saw his new National Geographic film Free Solo about his El Capitan ascent, it is a really epic story and highly recommended.
