Fargo needs a landmark. It should be something that when people see they'll instantly go "Fargo". It has to be larger than life. Landmarks just simply are. It should represent the people of Fargo, the drive and ambitions of the region and the cities eventual move to a more and more metropolitan/cosmopolitan growing technology center. It should emit our dreams and aspirations and declare to the world, FARGO has arrived. It, yes, is a bold statement and such forth, the landmark needs to be bold.

It should not be:

A statue of Marge Gunderson.
A larger than life wood chipper.
Anything to do with the movie Fargo.
Anything that is similar to a tractor, barn or silo.
Have anything added to it to lower its significance (i.e. Adding a Time/Temp digital readout on the side).
