River Riddle is a sculptural representation of an old 8th century riddle. The riddle states, "A farmer is standing on the bank of a river, with a fox, a chicken, and a bag of grain. He needs to get to the other side of the river, taking the fox, the hen, and the bag of grain with him. However, the boat used to cross the river is only large enough to carry the farmer and one of the things he needs to take with him, so he will need to make several trips in order to get everything across. In addition, he cannot leave the fox unattended with the chicken, or else the fox will eat the chicken; and he cannot leave the chicken unattended with the grain, or else the chicken will eat the grain. The fox is not particularly partial to grain, and may be left alone with it. How can he get everything across the river without anything being eaten?" This conundrum highlights the issue of inefficiency in the transportation and trade industry, and illustrates the complexity of that system.
