Don't forget the inner bark, from Cottonwood trees! It was supposed to help feed some early travelers around these parts. I've never tried it, but suspect that it would be a bit different than a Quarter Pounder, with Cheese. I'll opt for the local Deer and Turkey opportunities, and supplement with the other bounties of the land. Of course, this would only be a last resort situation, otherwise FEMA would take care of me, right?
