Road Sign Math

This week on Road Sign Math continues to be brought to you by Dave Oosterhuis and his wife Phoebe. This sign brings us closer to their final destination as they cross into Iowa, as it points the way to a rather interesting set of cities. New Hampton sounds like a place where you could get lobster and blueberries, Riceville is obviously the home of Condoleezza Rice. Cresco really caught my eye though. There seems to be no connection to Crisco, but it does lay claim on being Iowa’s Year ‘Round Playground!

This sign is elegant and understated in it’s mathematical connection. It also has a unique quality in the ordering. Typically road signs progress in shortest distance on top to longest distance on the bottom. Here, order was thrown to the window and chaos ruled.

This sign was found in Iowa on highway 63 southbound as it connects with highway 9, just south of Lime Springs. The GPS coordinates are approximated at N43 22 15.7 W92 17 54.0. See sign on map!
