The first match, Brenda and I ever held, had a thunderstorm right at the middle. When we were serving lunch no less so everyone had to scramble to get under the tents or the covered shooting lines, food in hand. Rain happens. Best one can do, is be careful, try to be safe and have a good laugh and good memories when it is all over.
A good point to remember, no matter how good you are, you can’t win them all and sometimes the weather or breakdowns or just plain bad luck ensures that.
