> The term external boundary, as used in section 287(a)(3) of the Act, means the land boundaries and the territorial sea of the United States extending 12 nautical miles from the baselines of the United States determined in accordance with international law.
What does that mean? That means that the 100-mile radius does not start from the Chesapeake Bay, it starts from about 13 miles off the Eastern Shore. Washington, D.C., for example, is not within this zone. Nor is Chicago or any part of Illinois within the zone--Lake Michigan doesn't have any 12-nautical mile basis to start counting from.
