Had a similar deal a few weeks ago. Went over for a pre re-opening tour of my course on the east side of Dallas, and police helicopters were all over. An armed bank robber was hiding in the woods behind 3 green, so the police had us leave the course until the search was over.
Even more unusual, for me, was opening day, some guy asked me to autograph his golf hat. Then, he followed me to the car and had me autograph some other stuff. Seemed a bit off his rocker to me. A few days later, he jumped to his death off a bridge.
