I'm half joking.
I'm no eating no carrion, I am not a crow.
We'd probably thieve loads of tinned food first, then get books on how to grow plants, and what plants you can eat.
People don't have enough adventure, people say they like the idea, but they never DO IT. THEY SAY IT'LL NEVER HAPPEN, IT'LL NEVER WORK!
WELL ADVENTURE TIME.
"It won't end well".
Well, wouldn't it be lovely if we tried?
EDIT: We don't need to thief food REALLY, we could maybe buy the first lot.
