The 87 Roadtrip

This roadtrip is scheduled to take place on Tuesday, 28 March 2006, which just happens to be the 87th day of 2006. [31 days in January plus 28 days in February plus 28 days in March equals 87 days]

There is nothing significant about the number 87; however, Arizona does have highways 87, 187, 287, 387 and 587 that are found south of the Valley of the Sun.

The roadtrip has a non-87 component to it and that is a visit the San Tan Regional Park located in the southeastern part of Maricopa County.

Note: AZ Hwy-487 has been "de-commissioned" and there has never been an AZ Hwy-687. AZ Hwy-87 is a north/south state route that has a southerm terminus just south of Eloy and a northern terminus located in Navajo County at Second Mesa. {Wikipedia.org:: Arizona State Route 87}

Math Bit

RoadHacker is collecting highway signs that are either prime numbers or square numbers.

   prime factorizations
   --------------------
    87 = 3 x 29
   187 = 5 x 37
   287 = 7 x 41
   387 = 3 x 3 x 43
   487 is prime
   587 is prime
   687 = 3 x 229
    
   there are no square number highways

The roadtrip will result in two prime number highway signs: AZ Hwy-587 and AZ Hwy-79.
