Close, but NO Cigar?

        Eagle-Eye Kat had spotted a tree, overhanging the Canal.  She put one of my Sticks to an unorthodox use to snag a fruit or two.
        I said they looked more like Plums than Crab Apples and, ever the adventurous palate I tasted one and confirmed my diagnosis.
BUT
       When one hears a name like "Greengage" the last thing one expects is a yellow fruit - however - seems that's what they were.
