I'm not sure there is a lot to learn from Rudolph. Admittedly E&E doesn't interest me much but a cursory examination of Rudolph's "survival" methods shows me that:

There are half-smoked cigarette butts and food to be scrounged out of dumpsters.
You can steal vegetables out of gardens and grain out of silos if nobody is watching.
Move at night and you lessen the chance that somebody can see you.
You can greatly increase your chances of avoiding capture if you are willing to live like a rodent.

Big deal. Any transient can tell you that. Even I could probably figure those things out without much effort. Throw in his repugnant philosophy and criminal actions and IMO he's just not worth studying.
