BARS::8 Miles From Catalina in Oro Valley, Arizona

This road sign is on northbound AZ Hwy-77 in Oro Valley, Arizona. This road sign was photographed the day after Pi Day 2013.

The road sign says...

   +-----------------+
   | Catalina      8 |
   | Jct. SR 79   12 |
   | Jct. US 70   90 |
   +-----------------+
   the numbers are:  8  79  70  12 90

   the math is:  12 - 90 / (79 - 70) = cuberoot(8)

   more math:  (8 * 12) - 90 = sqrt(79 - 70)!
