Has anyone heard what was going on today by Coyle Field? I some how got between two road blocks on Stephenson Road, around noon, and was politely asked to leave when I reached two Airforce SUVs parked across the road. There was a flurry of ground activity and several helicopters were skimming the tree tops. All I was told by one of the security teams was that there was a military operation and that I must leave the area.
