### BARS::No Trespassing at Town Lake in Tempe, Arizona

This no trespassing sign is on the northside of Town Lake across from the Tempe Center For the Arts in Tempe, Arizona.

The no trespassing sign says...

```   +-------------------------------------+
|          NO TRESPASSING             |
|            violators                |
|        will be prosecuted           |
|      up to \$1000 fine and/or        |
|       6 months imprisonment         |
|      ARS 13-1502 and 13-1602        |
| flood control dist. of Maricopa Co. |
+-------------------------------------+
```
```   the numbers are:  1000  6  13   1502  13  1602

the math is:  1000 / (1602 - 1502) = avg({13 - 6, 13})

observe...
1602 - 1502 = 100
1000 / 100 = 10
13 - 6 = 7
avg(7, 13) = (7 + 13) / 2 = 20 / 2 = 10
```
##### Update::2008.11.17

TempeHiker found the same sign at Granite Reef Diversion Dam on 17 November 2008. The numbers in the sign were re-examined resulting in the following equations.

```   the numbers are:  1000  6  13  1502  13  1602

the math is:  sqrt(sqrt(13 * 6 + 13 - sqrt(1602 - 1502))) = log(1000)

more math:  (log(sqrt(1602 - 1502)) * log(1000) * 13 / 13)! = 6
```
