Fun fact today for all you bug-lovers out there: every single summer, about
18 TRILLION mayflies all hatch at the same time on the upper Mississippi
River, and they create a swarm so huge and disgusting that it can appear on
weather radars. Just the dead ones can pile up deep enough to shut down
bridges and fill up entire parking lots three feet deep.

So, knowing this makes me wonder… if every year brings 18 TRILLION new
mayflies to the river, why does ANYBODY live anywhere near the Mississippi
River at all??
