I read Hunter Thompson’s “Hell’s Angels” when I was 15. It was a real eye-opener for a youngster from a small town. Thompson was noted for his gonzo lifestyle but the guy could be a very eloquent writer when the mood struck him. Recommended if you haven’t read it. Notable is Thompson’s description of a Hell’s Angel without his bike as being a sad sight, just another small time loser..
Yep, alone he is just another homeless looking dude with a ponch and sagging tats.
They are also mentioned in the Tom Wolfe book about Ken Kesey and the Merry Pranksters - "The Electric Kool-Aid Test".
The Hells Angels were usually very intimidating to other people during the 1960s but according to the book, the Merry Pranksters were so darn weird that even the Hells Angels were taken aback.
