A bunch of us Americans crossed the border into Mexican territory without visa or passport, or even a by-your-leave by the Mexican Government and its People. See how they like it when the table is turned on them!!! http://en.wikipedia.org/wiki/Coronado_Islands The Coronado Islands (Islas Coronado or Islas Coronados) are a group of four islands off the northwest coast of the Mexican state of Baja California. Battered by the wind and waves, they are largely infertile and uninhabited except for a small military detachment and a few lighthouse keepers. The islands lie between 25.6 and 32 kilometers south of the entrance to San Diego bay, but only 13.6 kilometers from the Mexican mainland.
