Ted is a world traveller. This summer, however, he decided to see the good old U.S.A.
On his vacation he went to the northernmost, southermost,
easternmost and westernmost points in the U.S. (not necessarily in that order).
He did it without ever crossing a landborder between states and only leaving U.S. controlled territory once.
How did he do it?
(In reply to re: Are you sure what these geographic points are ?
I think I got it. East and west can be measured relative to the prime meridian. The eastern most point and western most point are then the two spots mentioned in your post. With the eastern, western and northern most points all in Alaska, it is easy to accomplish the task by visiting all three points and then leaving for Hawaii.
