I was here at my house in Valpo, Indiana. Working on a website when my house shook briefly. It wasn’t any normal shake, and it was enough for me to get up and go check on things.
Then I receive and IM from a buddy in Illinois, asking me if I felt that. Indeed I did. Then I find this.

Just wondering if anyone else felt it
