Even if Brian does speak French it won't really help as they speak a strange English-French Canadian hybrid. But not exclusively. My eldest nephew was born in Ft. Kent in 1984 and I spent a lot of time up there. I took Spanish in school and got along just fine. (you will hear phrases such as "Trow me down da stairs my purse, eh?")
The only thing I will say about Aroostook County is you better like being waaaaaay far out into no-man's-land and I hope you don't need to look for work; there are few jobs up there.
