Dave Oosterhuis and his wife Phoebe captured this sign on a recent trip to homecoming. Dave would like to express excitement for the event with a splendid "Go Hawks". It excites me greatly though that another couple are sharing in the enjoyment of hunting mathematicaly signficant roadsigns. As the old saying goes, couples that do math together, stay together.



The math on this sign is as easy as "falling off a log". The size of the numbers and the lack of anything to distract your attention make this sign nearly glow in it's mathematical obviousness.

$$\sqrt {16} = 4$$

This sign was found in Minnesota heading southbound on highway 52 just before the Pine Island.
