I pulled into my driveway, parked my car, got out and looked up at the sky, which i often do. i noticed a large number of what almost looked like streetlights in color and shape flying very high above me and said "what is that? hey what is that?!" to my wife and two kids. my sons have very good vision (the older one has 20/10), whereas mine is okay, but not perfect. my older son yelled, "what the hell! i don't know what that is." and my wife and younger son could not figure it out either. there seemed to be upwards of 20 lights with empty sky between them, if our recollection is correct. my kids ran toward the house scared, which is uncharacteristic of them to be afraid of anything, but they did not know what they were seeing. we all want to believe they were high flying birds or some military aircraft.
