Randy Weiss puts another one on the board for Massachusetts, now totaling 10 winning signs. His quest? To step in front of Pennsylvania, and he is only three away from matching Penn’s amazing 13 signs. This sign just oozes New England — Lexington, Concord, Cambridge.

Great math on this sign, some quick addition and mental gymnastics reveal the formula.

\sqrt {5 + 11} = 2^2

This sign is found at the entrance to route 2, where route 2 is a limited access highway, at Pleasant St. in Arlington, MA. The GPS coordinates are approximately N42 24 22.7 W71 09 47.9. See sign on map!

    Interestingly, the sqaure root of (11 - 2), + 2 = 5

    Love the site.
