It was probably worse than the Grasshopper Plague of 1874:

The invasion began in late July when without warning millions of grasshoppers, or Rocky Mountain locusts, descended on the prairies from the Dakotas to Texas. The insects arrived in swarms so large they blocked out the sun and sounded like a rainstorm. They ate crops out of the ground, as well as the wool from live sheep and clothing off people's backs. Paper, tree bark, and even wooden tool handles were devoured. Hoppers were reported to have been several inches deep on the ground and locomotives could not get traction because the insects made the rails too slippery.
Clearly, they've got nothing on hippy.
Ah, OK. Thanks. Shame, that. Was it because hippy ate all their food and drank all their beer?
