Compared to Park Cruising: What Happens When we Wander Off the Path Leo Herrera's (analog) Cruising is a bit more of a paint by numbers, ain't cruising grand sort of book -- but a well executed one. Part memoir, part how-to guide, part advocacy, (analog) Cruising covers twenty four years of Herrera's cruising sex life in eight different "biomes" -- Bathhouse, Street, Nature, Darkroom, Arcade, Sex Club, and Bar.
Herrera interleaves his own successes and failtures over the years with a general description of each biome -- what you can expect, the unspoken etiquette involved, how to navigate the world of non-verbal consent. For any cis gay man considering entering this world, (analog) Cruising provides one man's version of a well thought out guide.
The book does seem to be written for cis gay men. Trans lives are mentioned sparingly, although Herrera does go out of his way to make it clear that cruising areas should make trans folks (and elders) feel welcome -- where welcome means free to not be harassed and use the facilities in peace. The implicit message to the book's cis readers is you need to tolerate trans folks, but you dont have to fuck them.
Trans people don't merit many other mentions -- there's acknowledgment that one sex club got its start as a "female impersonators" club without exploring what that might have meant and a mention of a some drag mothers that taught Herrera the art of the cruise in San Francisco dives. Trans mascs and men looking for tips on how to navigate the hinted at transphobia will need to look elsewhere. No mention is made of the challenges faced by the handful of bathhouses with nights for trans femmes and women and how that's challenged the unwritten rules around non-verbal consent. No mention of the ways a young, self-closeted trans woman might find aspects of the scene challenging.
If the book piques your interest you'll probably enjoy it, but if you're already acquainted with the topic and scene(s) you won't find new ground broken.
