Alice Waters is well-known in the San Francisco Bay Area and beyond for founding the Berkeley restaurant Chez Panisse, and for championing local, organically-grown food.
She also created the Edible Schoolyard project at Martin Luther King, Jr. Middle Schoolin Berkeley, California, which is an educational program that centers around students growing and preparing their own food at school.
I briefly lived in Berkeley in 2008, in the neighborhood known as the Gourmet Ghetto (so-called because of the many wonderful markets, specialty food shops and restaurants).
Of course Chez Panisse is there and Martin Luther King Jr. Middle School's Edible Schoolyard garden, where I enjoyed occasional morning walks watching the squirrels taking the best figs from the fig tree. So I admire Alice Waters and what she has done for Berkeley, food, local farmers and the community.
A contour drawing is a nice exercise to try. Use a single line to make your drawing and don't lift your pen or pencil from the page. You are supposed to make a contour drawing without even looking at the page, but it's OK to cheat a little bit. This is a good way to stop thinking about what you are drawing, and just rely on your eye and your hand.
You will have to draw slowly to get a good drawing.
