Pleasant Math

Randy Weiss puts another one on the board for 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.
