When a visitor to your garden compliments you on your chenopodium as well as your tomatoes, you know he’s a hardcore forager. Where you see a blaze of summer beauty in a stand of day lilies, the hardcore forager sees fritters and cooked buds and a salad made with the tubers. A lake fringed with cattails is liable to bring paroxysms of joy in the hardcore forager. There are flour, vegetables, and even something for the pickle crock there, not to mention a meat course of fish or frog legs. Experienced foragers see food, medicine, and other useful things in every forest and field.
