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?
He starts off from haiwaii (most western and southern) he flies to Alaska (most northerly) and then across Canadian airspace (leaving U.S. controlled airspace) and lands in calais Maine (most easterly)
