Reminds me of that guy Ewell Gibbons who used to advertise Post Grape Nuts on TV..."Have you ever eaten a pine tree? Many parts are edible."

Orange, persimmon, and fig trees are domestic trees and one is unlikely to encounter them in the wilderness.

A survivalist will often rely on plants like Miner's Lettuce, dandelions, and pine nuts while trapping (or shooting) small animals like squirrels, rabbits, snakes etc.

Most suburban midpeninsula 'outdoors-people' are too squeamish to be true outdoor survivalists.

A Patagonia fleece jacket and a Swiss Army knife is all they need to validate their outdoorsman identity.

Wild mustard is another edible plant.

When we were in Hawaii, a local nature guide taught us how to identify psylosybin (magic mushrooms) in the wilds.

I imagine there are countless edible plants in the jungles of Hawaii.

In the American southwest, one can also eat cactus petals (usually roasted) and rattlesnakes (skinned and grilled).

I think it is only in suburban and urban areas where one must go to the grocery store out of necessity.

I would imagine there are also some edible insects in the forest.

Natives in South America and Africa eat various insects and when you come right down to it ecologically, the consumption of insects is one of the most direct and eco-friendly ways of procuring protein.

Acorns can also be made into a porridge after they are leached of tannins.

With so many oak trees in the area, why don't the vegan-minded fanatics explore this option as well?

The Ohlones made acorn porridge and in some ways, it is Palo Alto's true native cultural dish.

Surprisingly no foo-foo fusion restaurant has offered a variation of this traditional dish.
