Bay seniors still fantasizing living off the land might want to sign up for an edible food field trip with Feral Kevin (aka Kevin Feinstein) in the hills between Lafayette and the Caldecott. Possible menu choices include mushrooms, edible pollen, miners lettuce, thistles and chickweed. Next month’s foray is sold out. But Sunday March 2 appears to be available. Starts at 10 am. $20 on Goldstar.
