Dan Bock brings a second sign from Charlotte, North Carolina. This sign is from the Uptown area of Charlotte. You can see Charlotte's Hearst Tower in the background of this photo.



Big bonus points for Mr. Bock on this sign find for using the numbers in exactly the order they appear on the sign (top-down, left-right).

$$77 = 29 + 49 - \bigl( ( 1 + 3 - 5) \times (27 - 28) \bigl)$$

This sign is found on S. College St. at the corner of E. 4th Street.
