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
