Until a few weeks ago, the quaint Midwestern town of Madison, Indiana eluded me. Little did I know that I would stumble upon the Midwest’s most beautiful rivertown along the banks of the Ohio River. Not only is it surrounded by a lush green state park, but it also has the United States’ largest contiguous National Historic District with 133 blocks of antebellum homes, with big balconies still draped in 4th of July bunting, known as the Madison Historic Landmark District.
