It's a perfect day for a spring picnic! But-oh no!-the beautiful flowers make Bert sneeze! Ants march off with some of the goodies! A baseball lands-splat!-in the dessert and some bicycle racers zoom through, making a mess. And of course it begins to rain. But that's okay, because, as Bert points out, without rain it just wouldn't be spring! A rollicking, rhyming romp from start to finish.
