Footnotes:
1Penowa is also less than ten miles from Ohio.
2I'm not repeating myself! I'm not repeating myself! There really are two towns in Pennsylvania named State Line that border Maryland. (That's nothing. Arkansas has six towns named Crossroads and seven named Cross Roads.)
3Louisiana also lends part of its name to Texarkana , but it is over thirty miles away.
