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?
how about, he takes a ship (I think on the high seas a ship counts as US controlled territory)
from hawaii to alaska (covering south, west and north) Then flies to over Canada (outside US control) to Maine easternmost.
