I only find a few such places. Hawaii's really deep hole ends in Botswana. The far northern tip of Alaska would tunnel through to Antarctica. A spot about 20 miles south of Granada, Colorado and another spot about 5 miles southwest of Cheyenne Wells, Colorado could dig straight through to two tiny islands in the Indian Ocean. In Canada, the southeast corner of Alberta is the antipode of reasonably big Desolation Island.
