I know you said it's a clear night, but it's the only plausible explanation I can think of.

5 Million living in and around Dallas are wide awake after midnite

There is no heavy weather in the area so likely it's some dick being a dick.

that Jerry Jones has selected Johnny Manziel as backup quarterback for the Cowboys?

This is spooky!

I know that it is causing some anxiety, particularly in light of recent world events.

Plus, it runs the risk of "boy who cried wolf" syndrome, meaning people will ignore the sirens if something does happen.

have. Just that there are sirens going off.

Post if anything is found out.

This is weird.

maybe somebody hacked into the system

That is weird.

Shrewd move Kim. Shrewd move.

a lot of babies will be born in or about January 8, 2018

the more and more rounds of this-the more I think this might be some hacking event-seems like it would be pretty easy to shut it down once it you knew it went off

A Bit More:

City of Dallas says:


System malfunction with City of Dallas siren system. Crews working to fix. No emergency. Please do NOT call 911. Thank you.

Your video was exactly how it sounded across Dallas

---now there have been about 7 rounds of scattered sirens going on in the distance that seem to be shut down sooner rather than the first round that lasted for a good 15 minutes

if that were listening to that several times in one night.

so far the casualties include two prairie dogs, one longhorn, and a couple of UT coeds who were hitch hiking to the beach.

This is nuts.

Especially with us boomers who were trained to "duck and cover."

Not that "ducking and covering" would have helped one iota during a nuclear attack, but it gave everyone the illusion of a positive reaction to being obliterated by nuclear warheads. Ahhhhhh....memories of being a scared shitless youth.

I was a little hurt that my parents didn't pick that option

not normal

think that speaks volumes about you

Heads up from @CityOfDallas: "Fire dispatch crews are manually shutting off the sirens and a complete shutdown could take up to three hours"

...and we all got a good nites sleep

They are still going about 1 1/2 hours after the began-sporadically-somebody has really hacked the system

I can sympathize. No matter how clear the weather the sound of those sirens make you feel odd. The deep seated feeling of having to be very cautious is hard on a person. I hope it stops soon for you because no amount of reassurance can take that feeling away, the only thing that can fix it is for it to stop.

Duck and Cover was bad but my first and longest memory are the tornado sirens.
