We were driving through the area and this sign caught our eye. There are a whole series of signs erected by the group , Rural History Buffs of Marion County. We weren't aware stage lines ran through the area and then found this story from the State Historical Society of Iowa. This may not have been the same stageline, but an interesting story of travel at the time.
This is an excerpt of a story written by Kenneth E Colton
On the 2,3rd of October, Monday, I think, 1865 last, I saw Elijah Hayden and spoke to him about taking passage [on the stage], 1 told him that there would be two of us, 1 inquired the fare and he stated it would be 3,50 a passenger. When I stated that there would be two of us, he put the fare at six dollars, three dollars a piece. He. then directed us to see Mr, Robert Boyd, the local agent of tho Company here, to whom [we were] to pay the fare and put our names on the waybill, I then called upon Mr, Boyd, stated to him the conversation between Mr, Hayden and myself, at least as to the price. He took my name and I paid him three dollars. About some where along 
after 1 o'clock the coach drove up to my house, I put in my valise and took a seat in the coach. We got to Knoxville, Marion County, a little after dark, possibly 7 o'clock, possibly 8, somewhere between 7 and 8 o'clock. We got supper there, remained there half an hour, the coach drove around to the Hotel door and I with other passengers got in again, I took the front seat, first set down in the middle seat, a gent on each side of me, I desired to smoke and took the outside seat. We had barely got seated, got ourselves situated. The coach, I think, was travelling in a slow trot, or the horses were. The next thing I knew, I saw fire fly, all the passengers were piled up together. I did not know whether we had been struck with lightning or what, the senses were all knocked out of me. The Coach turned over to the right hand side. The way I was sitting, I was riding backwards, and by some means got my head out of tho window. The coach was lying upon the side I was trying to get out of, but could not do so, on account of not having the use of my left arm. I could not assist myself with my left arm and had to call for help, I thought at the time my left arm was broken, for I could not use it.
