BARS::Off-By-One Heading to Pierce Ferry in Arizona

This road sign is located in northwest Arizona off of Route 66.

The road sign says...

   +---------------------+
   | 52 Pierce Ferry     |
   | 39 Hualpai Wash     |
   | 42 Greggs Hideout   |
   | 44 Salt Spring Wash |
   +---------------------+

   the numbers are:  52  39  42  44

   the off-by-one math is:  sqrt(39 + 42) + 44 = 52+1

   observe...
      39 + 42 = 81
      sqrt(81) = 9
      9 + 44 = 53, which is 1 more than 52
