Buffalo City, Arkansas is due east of Fayetteville and roughly halfway between Mountain View and Mountain Home:

You'll probaby want to zoom out to a wider area to get an idea of just where this is...

I knew there was a Buffalo River up there in the Ozarks, then ran a search on Mapquest and found the "City" (undoubtedly a rather small town).
