Quite a few memorable portraits here. Especially liked the poignant portrait of Nadine, a prostitute the author met who later died at 19 (actually cried after reading that one). But the generalities ("All gearjammers like to do this" and "All truckers like that") and the cowboy metaphor became wearing. Similar themes repeat too often, always coming back in a jumble, as if the copy were rushed to print.
Also, probably because it was written in the mid-70s, the sexism and racism seemed a jarring -- even more so because I couldn't tell if the author felt that way or if she was simply emulating the trucker's attitudes and speech (she used terms like Black Mammy, nigra, savage indians, etc)...since the terms weren't attributed it's hard to tell.
But if you're interested at all in the trucker's lifestyle and his/her history, this is a unique slice of Americana. And the photos, quite amazing at times, show a world long gone.
