The park sign says...

```   +------------------+
| Day Use     5.00 |
| <- Rec Area    1 |
| Rec Area 2    -> |
| Rec Area 3    -> |
| Cabins 1-15   -> |
| <-  camping   -> |
| RV Park       -> |
| Hiking Trails -> |
| <- Nature Trail  |
+------------------+
```
```   the numbers are:  5  1  2  3  1  15

the math is:  sqrt((5 - 1) * (1 + 15)) = 2^3

more math:  (15 - 5 + 1 + 1) / 2 = 3!

more math:  sqrt(5 - 1) * 3 - 2 = sqrt(1 + 15)

rsAgeEval:  15 * 3 + 2 + 3 + 1 - 1 = 50
* RoadHacker was 50 years young when he found this sign.

rs42Eval:  15 * 3 - 5 + 2 + 1 - 1 = 42

```   the numbers are:  5  1  2  3  1  15

rsAgeEval:  3 * 15 + 5 + 2 + 1 - 1 = 52
* MathBabbler was 52 years young when he found this equation

rsStateEval:  3 * 15 + 5 - 2 + 1 - 1 = 48
* Arizona was the 48th state admitted to the Union and Hualapai
Mountain Park is in Arizona

rsPhiEval:  (1 + sqrt(5)) / (15 / 3 -2 - 1) = Phi
* Phi is the golden ratio and it approximates 1.61803399

rsPiEval:  (15 + 3! + 1) / (5 + 2 * 1) = Pi
* 22/7 approximates Pi (3.14) rounded to nearest hundredth
