text: ### BARS::Pi Sign on AZ Hwy-73 in Arizona
  
  This road sign is on prime number AZ Hwy-73 in Arizona.
  
  ```   +--------------------------+
  | W.M.A.T. Fairgrounds   2 |
  | Tonto Lake            41 |
  | Pacheta Lake          41 |
  | Maverick              39 |
  | Drift Fence Lake      44 |
  | Reservation Lake      47 |
  | Hurricane Lake        45 |
  +--------------------------+
  ```
  ```   the numbers are:  2  41  41  39  44  47  45
  
  the math is:  (44 - 41)! = 2 + (47 - 45) + (41 - 39)
  
  observe...  44 - 41 = 3  and  3! = 3 * 2 * 1 = 6
  
  rsPiEval:  44 / ((47 - 41) * (41 - 39) + 2) = Pi (3.14)
  * 22/7 approximates Pi (3.14) rounded to nearest hundredth
  
  [solve for 'n']  44 / ((47 - 41) * (n - 39) + 2) = Pi (3.14)
  ```
  
  Note: This road sign was found on the Pi Day 2008 roadtrip.
  
  ##### BAB Milestone
  
  This was the 400th BARS (Basic Arithmetic Road Sign). It is also BAB #1461. As of 16 March 2008, approximately 27.4% of all BABs are BARS.
  
  ##### Update::2008.10.31
  
  The following math was discovered on 31 October 2008 after this BARS was selected as one of the BARS of the Week for Week #11 of the fall 2008 semester.
  
  ```   the numbers are:  2  41  41  39  44  47  45
  
  the math is:  (47 + 45 - 41 - 41) / (44 - 39) = 2
  
  rsPhiEval:  (2 - 41 / 41 + sqrt(44 - 39)) / (47 - 45) = Phi
  * Phi is the golden ratio and it approximates 1.61803399
  
  rsHwyEval:  41 + 41 - 2 - (44 - 39) - (47 - 45) = 73
  * This sign was found on AZ Hwy-73.
  
  rsAgeEval:  (47 - 39) * (2 * (44 - 41)) + sqrt(45 - 41) = 50
  * RoadHacker was 50 years young when he found this sign.
  
  more math:  sqrt(sqrt(44 + 39 - (47 - 45))) - 41 / 41 = 2
  
  more math:  (44 - 41)! - (41 - 39) - (47 - 45)  = 2
  
  more math:  (47 - 41)! / (44 - 39)! - (45 - 41) = 2
  ```
  ##### Update::2009.03.08
  
  This BARS was selected to be one of the BARS of the Week for week #8 of the spring 2009 semester.
  
  ```   the numbers are:  2  41  41  39  44  47  45
  
  rs42Eval:  (41 + 41) / 2 + log((44 - 39) * (47 - 45)) = 42
  * 42 is the "Answer to Life, the Universe, and Everything"
  
  rsAgeEval: (41 + 41) / 2 + (44 - 39) * (47 - 45) = 51
  * MathBabbler was 51 years young when he found this equation.
  
  more math:  (cuberoot(47 - 39) + (45 - 41)) / 2 = 44 - 41
  
  [solve for 'n']  (cuberoot(47 - n) + (45 - 41)) / 2 = 44 - 41
