Cowards!
Lettin’ a little thunderstorm scare ‘em.
Where I live we have tornadoes.
They’re worse
Before I moved to this tropical paradise (Northern Virginia) I lived in Indiana where, the records show, they have derechos, thunderstorms, tropical storms, hurricanes, and tornadoes ~ albeit with a different frequency of occurrence. They also have massive floods that have several times in my life covered half the state with vast sheets of water up to your neck.
What I"ve learned over the years is to avoid scheduling large events in areas where there's a high probability of weather anomalies at that time of year. Doesn't matter if it hasn't rained in 10 years, if the statistics say there's a high probability of bad weather, then there's no sense taking that risk.
