Oh, my land, these little things are out in FULL force and make the most horrendous noise. They are so plentiful and loud over at Darah's house, they make your ears ache. Seems after the rain of a couple days ago, they started flourishing and are here at Carol's house too, Setting up a chorus to beat the band. They are in full voice, then all of a sudden they all stop at once, how do they do that, why is there not just one that will keep it up while all the rest are silent??? Suppose there is a scientific reason, but to us laymen, it is a mystery!!! But it is definitely the sound of Summer in Iowa!!
