It's not for me and for most people perhaps, but perfectly good food can be had out of dumpsters behind markets. The rats that ran over the food in the dumpster are only slightly less classy than the ones that ran over it within the market.

Roadkill, especially feral pigs, rabbits, and deer are perfectly acceptable if you are sure that their demise was recent. Cooking, however, would be needed unless one is especially hard core. Not for me either, but just sayin'.

This course offers instruction on how to live off the land.
