What is this strange ring floating in the sky of McKinney in the Dallas-Fort Worth area?
It happened during a lightning storm near U.S. Route 75 and the Sam Rayburn Tollway.
NBC 5 Meteorologist Grant Johnston said this was likely a burst of exhaust from a big-rig with dual exhaust stacks on the overpass. Sorry but this is just too funny!
I would rather think that a lighting struck a transformer in a tree and caused a smoke ring.
