[Ezekiel]

So many mayflies hatched at once near the Mississippi River Sunday night

Which was June 7th.

I was reminded of what the White Rabbit exclaimed:

"I'm late! I'm late! For a very important date! No time to say hello, goodbye! I'm late! I'm late! I'm late!"

I'll raise you one Mayfly swarm for Black Fly swarm
