Randy Weiss puts another constant on the board for Massachusetts! This sign confounded him for a while searching for some mathematical relationship, and then it dawned on him that it contained the somewhat common 22/7 combination.

By far the most common approximation of Pi is done again.
{ { 12 + 9 + 1} \over 7 } \approx \pi
This sign is on eastbound I-90, Mass Pike at exit 12. The GPS coordinates are approximately N42.28472 W71.50069. See sign on map!
