This weekend’s theme is plants. (So was last weekend’s theme at the Cooley abode, as will be the next dozen or so weekends, but let’s not quibble over such details. It’s the weekend.) There’s a sale (plants), an ale fest (ale starts as a plant), Earth Day (plants), morel hunting (the fungus grows close to plants) and — trivia. Well, four out of five. Enjoy the weekend.
