That bug swarm reminds me of the mosquito "clouds" that I used to see when I lived in Minnesota! We'd gathered outside in the evenings for a family meal, look up, and see a dark cloud of them approaching. We'd pull out the bug spray and light the torches.
Used to have an old Ford Galaxie in the yard that burnt as much oil as gas. Dad would fire it up to help chase 'em away.
Kinda one of those, " You might be a redneck if..." stories.
