And don't for one minute believe that old line about God not being able to hit a one-iron. He can, and he will. If you can hear thunder, that means lightning is in your area. If you get caught out on the course when the sky opens up, seek shelter under a roof, preferably not a metal structure. And don't believe the old wives tale that says you're safe if you park in a grove of trees.
Trees are the tallest structures on the course, so they're lightning magnets.
There's no safe place on the course. Wear loose-fitting clothes, and wrap yourself in multiple layers of clothing. Wear a hat. So keep your head covered. As far as mittens and ear muffs, well, that's up to you.
