Q: The word "marten," as in the animal, consists of the beginning letters of "Mississippi," "Arkansas," "Texas," and "New Mexico"; you can actually drive from Mississippi to Arkansas to Texas to New Mexico in that order. What is the longest common English word you can spell by taking the beginning letters of consecutive states in order as you travel through them? Puzzlemaster Will Shortz's answer has eight letters, but maybe you can top that.I see a number of ways to match Will's answer but I'm still working on a way to top him.
Edit: The first word I found was millions, hence the clue above about "a number"
