That calendar was one of the things we need to notice IMO, and that's why I keep thinking of those balloons. I'm trying to be practical, not hysterical. I guess what I'm hoping for is that security guards remember to look up once in a while in the day time and maybe run sweeping search lights into the airspace around sensitive targets at night. Some businesses do that just to attract customers, so it can't cost too much.
I know. If I thought you were going nutso on me, then I would start to worry. :-)
Forgive me for "using" you to speak to anyone who will take the time to listen.
