Each word below needs two letters added to it to make either a US state or Canadian province/territory anagram. eg. MAN + EI = MAINE or CUBE + EQ = QUEBEC. Starting with HAD + IO, work your way through. Each correct answer will reveal the extra letters needed for the next clue.
If you get stuck, you will have to try to guess another answer without the benefit of knowing the extra letters!
Shaded answers are locations that contain more than one word.
