Bristol-Cruiser
Super Anarchist
The study below was mentioned on CSF but is worth a more general look. It is a PhD thesis done in Oz in 1985 (pub date, likely several years research before). Be warned, it is more than 300 pages not counting the appendices that take its close to 500, but it has a lot of good insights in it. The author concludes that cruisers are social deviants but on the good side. He talks about how cruising is changing, remembering this work is almost 40 years old. One telling stat in the appendix is that the average age of the cruisers surveyed was 43! Might be more like 63 now. There is no doubt that extended cruising is easier today - navigation and self steering just to mention two areas. I think this has allowed more, and older, folks to be cruisers, often after 30+ years of hard work to get the means to cruise. Working so long and successfully suggests that they are a lot less socially deviant than earlier generations of cruisers.
