Pat, I read Euell Gibbons as a kid. Always wanted to live off the land.
My kid (17, so not so much a kid) always asks what anything green is. He "caught" me one year by asking the produce manager where the dock and dandelion greens were. He'd wanted to surprise me with a salad.
That was a fun discussion. He'd never noticed me pulling small leaves on our walks, for nine years.
Do you have/now of some good sites to ID wild food with good pictures?
