Lincoln's patent

[LincolnMan]

I’ve read and heard two seperate incidents in Lincoln’s life that provided the inspiration for his boat invention. Both stories are the same esentially- with Lincoln observing vessels getting stuck in the water. He is said to have assisted with the freeing of one those boats. The big difference with the stories is one took place on the Sangamon River and the other on the Detroit River. Of course, both incidents could have been true.
