The road sign says...

+----------------------------------+ | Casa Grande Ruins Natl Mon 14 | | Coolidge 16 | | Florence 23 | +----------------------------------+ the numbers are: 14 16 23 off-by-one: sqrt(23 - 14) = sqrt(16) - 1 ...or... off-by-one: 23 / (14 / sqrt(sqrt(16))) = 23 / (14 / 2) = 23 / 7 (23 - 1) / 7 approximates Pi## Casa Grande Ruins:: Great House

RoadHacker is revisiting this spot for Pi Day 2013. This BARS was BARS number 101. On 10 March 2013 there were 769 BARS.

the numbers are: 14 16 23 rsCardinalityEval: sqrt(23 - 14)! / sqrt(sqrt(16)) = 3 * There are 3 numbers in the road sign. BARSfunc rsCardinalityEval: sum_digits(23) + 14 - 16 = 3 * There are 3 numbers in the road sign. * sum_digits(n) = sum the digits of n domain: n must be a prime number BARSfunc off-by-one rsAgeEval: 14 + 16 + 23 = 53 - 1 * RoadHacker was 49 years young when he found this road sign. He was 55 years young when he revisited the road sign. * avg(49, 55) = 52
