James Bernard brings only the 2nd ever mathematically significant roadsign from Colorado. Colorado is an amazingly challenging state to play Road Sign Math. Mr. Bernard had passed this sign many, many times. Every time he thought "darn, so close!"



Mr. Bernard churned on this sign for a while, and then it hit him! The cosine of 720 is 1!

$$\sqrt{24 + \cos((\sqrt{9})!)!} = 5$$

This sign is on Highway 40 in Colorado, about 25 miles north of I-70.
