You must've felt the earthquake that was a little northeast of Oklahoma City. They had a 5.6 Saturday night. I didn't feel it but an article said it was felt all the way to Tennessee and Wisconsin.
Trying to remember if my dogs barked last night around that time. I don't think so.

We definitely felt it here. I thought the cats would freak out but they didn't! I guess they just didn't know what it was. The whole house shook for about 15 seconds.

I didn't feel a thing but some people in Nixa said they felt it.
