still growing

We are gardening this summer, even with a very limited amount of sun.  Some things have been plentiful: peas, beans, artichokes, potatoes, green tomatoes.  Some have been mediocre: carrots, beets, peppers, chard.  Some things have been pathetic: zucchini, pumpkins, lettuce, squash.  How on earth could I NOT grow zucchini?  Most people can't get rid of all their zucchini!
