re: Recommend a hunting/outdoor related book

I met the guy that most of this book is about, Dave Hall, back in the 90's. He came and spoke to our Wildlife Law Enforcement class about all the undercover work he did infiltrating the Hell's Angels and cracking their walrus ivory smuggling operation in Alaska. He was one bad mofo. He talked about smoking meth with the leader and there being a human skull on his coffee table. he asked who's it was and the guy told him his ex-girlfriend.
