On the site of the Post Office stood a large, white-columned, three-storied house known as the Stage Coach Inn. Horses for the coaches were changed there and stabled across the road from the inn. As a coach approached Monticello, the coachman blew a loud blast on his horn for each passenger so the cook would know how many guests to expect for supper. The first Monticello Post Office was in the Glover house, which stands at the division of the Eatonton and Macon highways, and the tin mail slot remains in the kitchen wall of that old house.
