I am curious if question about purely illegal activities are on topic. The specific question I have in mind is about freight train hopping in the US (which I am pretty sure is illegal everywhere in the US). While I am not sure freight train hopping qualifies as part of TGO, before I ask that, I figured it would be better to sort out the legal aspect.
Some other examples of illegal activities that are more clearly part of TGO:
The location of illegal, but frequently used, bivy sites in Yosemite National Park
Strategies for overstaying the limit on nights camping in Joshua Tree National Park
Rock climbing route descriptions for closed cliffs
