Are the questions about naturism on topic here?
Naturism is often associated with sunbathing, which isn't a very activity (although being outdoor), but it includes also walking and swimming. But fishing doesn't involve very intensive movement, and is on topic anyway...
If naturism should be generally on-topic, which aspects of it should be on-topic in detail? Let's take geocaching. Even the questions about equipment and software are on-topic here, though some of them would be good candidates for more technical sites. Should we then allow also questions about legal aspects of naturism? Or about naturist clubs/communities?
edit
Naturism questions are actually on topic on Travel.SE. So what kind of questions would better fit here than there?
