Who tried them first

I am so wondering who was the first person that looked at some of the things growing wild and thought "Wow" I bet those things would be good to eat!
I'm refering to alot of spring time bounty in Maine.
Who was brave enough to actually cut a dandilion green out of the yard and cook it up.Not to say, I don't enjoy a few feeds of these delicious greens myself, with lots of butter and vinager. Man, do they have a bite or what? The bitterness is what makes them so good! But before summer is over we will be swearing at these plants for taking over our yards with yellow flowers!And causing lots of grief with alergies.
Next comes the fiddlehead. One of the best parts of spring. We all wait in anticpation for the first one to pop up , then look out!! The riverbanks are full of two legged scavangers with plastic shopping bags , trying to get a fresh feed for supper!! My grandpa had an old saying " if you listen, you can here them growing behind you as you pick"Now I know what he meant, they grow almost as fast as you can get pick em'. Everyone has a private spot , and only share it when they have more then they need for themselves.These locations get passed on from generation to generation.
Just before the fiddleheads arrive we have what is known as smelting season. As soon as the ice starts to melt everyone heads to the mouth of the rivers and dips smelts. Usually this takes place after dark, with carloads of people ready to get their limit. Of course over the years this changes, was a time it was a gallon a person. Now you get a 2 quart limit, or 200 smelts ..whichever comes first. I'll stick to the 2 quarts . I'm thinking who in their right mind would stand there and actually count out 200 three inch fish??
