Goes back over a lot of history that Matt Baume has covered in his YouTube channel, but it's still worth reading/listening to if you've seen those videos. If you haven't seen Baume's work already, this is a great book to pick up. Well researched and well constructed.
Perfectly blends together historical narrative, personal experience, social commentary, philosophy and legal knowledge.
Cruising, and particularly park cruising is a tough subject to write about as it is, let alone to produce a book that a person with no knowledge of the subject - besides what they've passively imbibed - can understand and learn from.
