Last trip to the range was, "Shattered Sword: The Untold Story of the Battle of Midway".
But it is an incredibly boring audio book (and probably not much better to read), though a very thorough and informative book. It was actually distracting to me - not because the book wasn't processable, but because I wanted to pay attention to what I was hearing. I did not want to just have it as background noise.
So, I skipped back a few minutes while walking out to my targets and went to music. "Upbeat alternative" was the playlist of choice. What, exactly, was played, I do not recall. But it was mostly '80s, '90s, and early 2000s rock/alt, with a couple Pink Floyd songs mixed in.
