On the day prior to Pi Day 2007, an Artie Artichoke doll was used as a decimal point to morph a NM Hwy-314 sign into a NM Hwy-3.14 sign. [Side-bar: Prior to 1937, NM Hwy-314 was Route 66.]

Four BARS (Basic Arithmetic Road Signs) were discovered, but only two are potential RoadSignMath.com submissions.

- Sky Harbor Signs From Pi Day 2007 Trip to Albuquerque, New Mexico
- Cochiti Road Sign on Pi Day 2007 in New Mexico
- Upcoming Exits on Eastbound I-40 Albuquerque, New Mexico
- Exits on Northbound I-25 in Albuquerque, New Mexico
One Phi road sign was discovered, but it required the creation of a

`reciprocal function`

.One parking sign along Route 66 in downtown Albuquerque that could be submitted to RoadSignMath.com.

Two square numbered highway signs were found: I-25 sign and NM Hwy-16 sign.

From "The Joy of Pi" page 21: In the Greek alphabet, π is the 16th letter (4 squared). In the English alphabet, 'p' is the 16th letter and 'i' is the 9th letter (3 squared). The sum of 16 and 9 is 25 (5 squared). The product of 16 and 9 is 144 (12 squared). 9 divided by 16 is 0.5625 (0.75 squared). It's no wonder we say, "Pi are squared!"

One prime numbered highway sign was found: NM Hwy-47 sign.

Two prime numbered MPH signs were found: 5 MPH sign inside a University of New Mexico parking garage; and a homemade 5 MPH sign at the vacant El Vado Motel located along Route 66.

Two

`16' 2'' clearance signs`

were found (#1 and #2). [sqrt(sqrt(16)) = 2]Four signs for which no math has been discovered.

Turquoise Trail road sign: 12, 23, 26, 46 [off-by-one Pi sign; 23/8] Turquoise Trail road sign: 1, 5, 7 [off-by-one] road sign: 599, 1 1/2, 3 1/2, 8 1/2, 10 hiking trail sign: 10, 1/3, 1 3/4, 1 3/4, 1 3/4Only off-by-one math has been found in the two road signs encountered along the Turquoise Trail. Math was found when the two road signs were combined. { Off-By-One Signs on the Turquoise Trail in New Mexico}

GDT took a picture of a NM Hwy-473 sign erroneously thinking 473 was a prime number.

GDT wrote Pi in snow on Sandia Mountain in the Chibola Forest. And he wrote a lava rock Pi at Volancos Day Use Area of the Petroglyph National Monument.

GDT has a BAB (Basic Arithmetic Bit) about the number 1957 and he found the number 1957 in a Rio Puerco Bridge sign. [ bridge picture]

We stopped at Cerrillos for a slice of pie, but the town wasn't up yet.

The number 1957 was found in the Welcome to Madrid sign. In Madrid, we stopped at Maggie's Diner for a slice of pie, but it was closed. [The diner was built for the Disney movie Wild Hogs.]

GDT signed the guest book at Tiny Town (a place where art dies to lives).

A tasty piece of blueberry pie was consumed at the Route 66 Diner.

Two Pi video clips were made on Pi Day 2007 and they have been uploaded to YouTube.com

account.Prior to leaving for Albuquerque, GDT learned that, to within half a percent, Pi seconds is a nanocentury. {BAB:: From Pi To Tom Duff To Nanocentury To NerdTests.com}

GDT claims any and all irrational Pi related behavior is due to the mathematical fact that Pi is an irrational number.
