BARS::I-10 Road Sign is a Golden RSeval (and off-by-one)

This road sign was discovered while driving west (north) on I-10.

The road sign says...

   +--------------+
   | Riggs Rd   7 |
   | 60 East   20 |
   | Phoenix   29 |
   +--------------+
   the numbers are:  60  7  20   29

   rsHwyEval:  20 - 60 / sqrt(29 + 7) = 10
   * This road sign was found on I-10

   off-by-one math: 60 / 20 + 7 = 29 + 1

Note: Golden RSevals are now called rsHwyEvals.

Update::2009.04.13

A better picture of this road sign was taken on Pi Day 2009. This updated picture contains a clearance sign on the overpass which includes the numbers 16 (feet) and 0 (inches).

   the numbers are:  16  0  60  7  20   29

   the math is:  (29 - 20) * 7 - 60 + 0! = sqrt(16)

   rsPiEval:  (60 / sqrt(29 - 20) + sqrt(sqrt(16))) / (7 + 0) = Pi
   * 22/7 approximates Pi (3.14) rounded to nearest hundredth

   rsAgeEval:  60 - 29 + 20 + 0 * (16 + 7) = 51
   * MathBabbler was 51 years young when he found this equation

   This BARS has great numbers and there are many more equations 
   to be found, but MathBabbler will find them at a later date.
