I didn't realize what they were at first, but there were a lot of nighthawks on my drove home tonight. Some were in small groups and others in larger. This was on 840 from Arno Rd exit to Veterans Pkwy exit. As I got off on Veterans and looked left, there was a distant large, dark flock of birds which I assumed to be nighthawks as well.
