BARS::Off-by-One Road Sign on Hwy-35 in Oregon

This road sign was found on OR Hwy-35 between Government Camp and Hood River in Oregon.

The road sign says...

   +---------------------+
   | <- Govt. Camp    16 |
   | Hood River  26   -> |
   +---------------------+
   |       Hwy-35        |
   +---------------------+
   the numbers are:  16   26   35

   the off-by-one math is:  sqrt(35 - 26) + 1 = sqrt(16)

   observe...
      35 - 26 = 9
      sqrt(9) = 3
      3 + 1 = sqrt(16) = 4
Update::2008.02.02

If we borrow one from 26 and add it to 35, we get three square numbers.

   the numbers are:  16  25  36

   the counting math is:  sqrt(16), sqrt(25), sqrt(36)

   observe...
      sqrt(16) = 4
      sqrt(25) = 5
      sqrt(36) = 6

   more math:  avg(sqrt(16), sqrt(36)) = sqrt(25)

   observe...
      avg(4, 6) = 10/2 = 5
