BARS::14 Mileages on One Road Sign in California

This road sign is on Parker Dam Road across the Colorado River from Parker, Arizona, in California.

The road sign says...

   +---------------------------------------------------+
   |                Straight Ahead To                  |
   |   ---------------------------------------------   |
   | River Shore    4 1/2   |  Big Bend         12     |
   | River Land     5       |  Californian      12 1/2 |
   | Emerald Cove   6 1/2   |  River Lodge      14     |
   | Rio            7       |  River Lodge Too  14 1/2 |
   | Rite Sport     8       |  Sunshine Resort  14 3/4 |
   | Windmill Park  8 1/2   |  Black Meadow     25     |
   | Echo Lodge     11      |  Havasu Palms     29     |
   +---------------------------------------------------+
   the numbers are:  4 1/2, 5, 6 1/2, 7, 8, 8 1/2, 11, 12, 
                     12 1/2, 14, 14 1/2, 14 3/4, 25, 29

   River Lodge Too?

   the math is:  
   A = (14 3/4 - 14 1/2) * (11 - 7) + (8 - 5) + (14 - 12) + (29 - 25) = 10
   B = (8 1/2 + 12 1/2 - 6 1/2 - 4 1/2) = 10
   A = B

   ...or using decimal numbers...

   A = (14.75 - 14.5) * (11 - 7) + (8 - 5) + (14 - 12) + (29 - 25) = 10
   B = (8.5 + 12.5 - 6.5 - 4.5) = 10
   A = B

   ...or (to copy and paste into Google's calculator)...

   (14.75-14.5)*(11-7)+(8-5)+(14-12)+(29-25)+4.5+6.5-8.5 = 12.5

   rsAgeEval: A = ((11 - 8) * (29 - 25)) / (1/4)) = 48
              B = sqrt(12.5 - 8.5) + (6.5 - 4.5) - (7 - 5) - (14 - 12) = 0
              A + B = 48
   * RoadHacker was 48 years young when he found this sign.

   rs42Eval:  A = ((11 - 8) * (29 - 25)) / (1/4)) = 48
              B = (12.5 - 8.5) + (6.5 - 4.5) + (7 - 5) - (14 - 12) = 6
              A - B = 42
