Should have waited 30 minutes after the last lightning siting before re-starting the game. If you see lightning at the 25 minute mark, the 30 minute count starts again. Here is the ASA link to their lightning policy. It is very hard to sit the 30 minutes when the sun is out and everyone wants to get the game going but it must be done.

This weekend there was a fisherman killed on a small lake only a few miles from where I live. A major storm blew through and this guy decided to wait out the storm in his boat while sitting in a cove on the lake. His partner in the boat was unharmed.
