Much of the information in How to Survive in the Woods is straightforward, even obvious — plan ahead, make sure someone knows where you are going, etc. — but these tidbits on berries, of all things, caught my eye:
Color test: White and yellow berries are poisonous 90% of the time, blue and black berries are good to eat 90% of the time (however, deadly nightshade berries are dark blue or black and they taste sweet, but a couple can kill you fairly quickly), and red berries are a 50/50 shot.Aggregate berries, (bumpy ones like raspberries, blackberries, etc.), are almost 100% good to eat. The only exception to that rule is a white berry that grows only in Alaska.
