I did it twice - big fun!
There are different types of balls, we had those shown here. They are like stones, flying much shorter with the irons.
Be careful to turn the bore at right angle for each shot, otherwise ball and light may separate - you'll find the light only.
The balls gloom well out of the rough, alas the event should be at new moon - any surrounding light will make it more difficult.
some ppl can hit the ball as well as in daylight, others struggle a lot. Overall, it's big fun if you have some knowledge of the course! It's awesome to see the ball flight similar to the vapour trail here.
