Edible or Unedible Plants?

Last night Kade and I attended a party hosted by the Hiking Meetup of Asheville. We ate a decent patty melt with a side of onion rings. The movie showing on the big screen was Into The Wild, based on the life story of Christopher McCandless and directed by Sean Penn. We had seen it before, so we ended up ducking out earlier than the rest of the guests. Two lines from the movie stand out. One, the words etched into a wood plank found on Christopher's bus in the wilds of Alaska:

Two years, he walks the earth. No phone, no pool, no pets, no cigarettes. Ultimate freedom. An extremist. An aesthetic voyager who's home is the road. So now, after two rambling years, comes the final and greatest adventure, The climatic battle to kill the false being within,Victoriously conclude the spiritual revolution. No longer to be poisoned by civilization, He flees, and walks alone upon the land to become lost in the wild. Alexander Supertramp (Christopher's pseudonym) May 1992

The other, during a poignant scene on the beach:

“I’ll paraphrase Thoreau here: Rather than love, than money, than faith, than fame, than fairness – give me truth.” Christopher McCandless
