Today I found a lovely sit spot under a big oak beside Liberty Creek, in a less-visited part of Malibu Creek State Park. Sadly, even here there was styrofoam litter, which I duly collected. On my way back to the car I thought I saw a bunch of tennis balls nestled among the mustard, and reached in to add them to my bag ‘o trash. But they were ripe calabazillas or stinking gourds (Cucurbita foetidissima). The vine had completely died back, leaving just the fruit. Tricked me!
