Laura Kalamets looked out a Canton restaurant window during a Valentine's Day lunch with her boyfriend and saw a public bus with an ad on its side that read: "Laura, Will You Marry Me?" It was signed "Mark" and included in smaller letters the words "and make me the happiest man in the world."
Kalamets says she thought she'd have a heart attack.
Mark Rose paid the transit agency $300 for the special ad and arranged for the bus to be parked in the right spot around noon on Monday.
The Repository newspaper of Canton reports the ad will remain in place for a week.
Now it has the additional message: "She said yes."
