Stroup, a vice president of a real estate title company, has taken his sons hunting since the oldest, Rob, was five years old. Rob, now 35 and a former Marine Corps sharpshooter, spotted the buck the day before his father was to arrive at the Carrizo Springs ranch. He shot video of the massive nontypical from 500 yards and sent his dad a still photo. "What he didn't do was show me the video, because he thought I'd be too excited and miss," Stroup says. "And he was probably right."
