I'm pretty sure this is the ferry I intended to take in 1982 while on a cross-country bicycle trip. When I got to the river some kids playing in a nearby yard told me, "he don't run the ferry no more". So I headed south to see if the ferry at Hickman was still running. It didn't look any more promising (as the picture shows) but it was, in fact, running, much in the way, it seems, the Belmont-Columbus ferry used to run. You signaled the ferry by flipping the sign to the white side.
I took this ferry in 1970 from MO side. The road deteriorated from paved to gravel as it got closer the Mississippi. The last half mile was just a dirt trail. I thought there was a bridge here, and when the road ended at the gravel river bank there was nothing. As I turned around to go back, an operator of a front end loader stacking logs called out to wait for the ferry. I looked harder, and sure enough, on the other side was the ferry unloading. When it came across, it jammed it's ramp into the gravel bank, good enough so you could drive on. That saved me a lot of driving.
