These highways signs were found in Bisbee, Arizona.

The highway signs say...

+------------+ +--------------+ +------------+ | AZ 80 West | | 16 FT - 6 IN | | AZ 80 East | | Old Bisbee | +--------------+ | Douglas | +------------+ +------------+the numbers are: 80 16 6 80 that math is: log(16 - 6) * 80 = 80 observe... 16 - 6 = 10 log(10) = 1 80 * 1 = 80## Updated::2011.03.19

This BARS was selected to be one of the BARSOTW (BARS Of The Week) for week nine of the spring 2011 semester.

MathBabbler spent Pi Day 2011 in Bisbee, Arizona.

During his Pi Day 2011 visit to Bisbee, MathBabbler returned to the spot of this BARS and took a picture that included two speed limit signs that resulted in MathBABs.us::BARS::AZ Hwy-80 Underpass With Speed Limit Signs in Bisbee, Arizona
