Wow!
We were driving home from the Farmy last night. Around 10pm we almost got rearended as we turned off Rte 7 to cross Bulls Bridge. We stopped to look at the street light by the dam. It had a vortex of flies that looked like a tornado, from the ground up to the light about 10' across swirling.
Thanks for posting this Aaron, we thought they were midges or mosquitos from the distance.
