I've only once seen an outbreak of locusts and I hope I'll never see one again, it still gives me the creeps more than a decade later. Everything covered in insects, as far as you could see. This was in Northern Canada, just South of Sudbury, near the Magnetawan river.

I'd never seen anything like that ever before, I had to stop for gas, saw a few insects land, went in to pay and by the time I wanted to go back to the car it was literally covered in insects, there was no way to get into it without bringing a few hundred of them along. I ended up waiting out the worst of it.

Horror movies really don't capture the feeling well.
