Strange that you are in FW and felt the quake, while I’m in Grapevine (NE of you) and didn’t feel a thing. I haven’t read any postings of others in the DFW area feeling the quake, other than you.
Arlington is the only other post on this thread that I've read that felt it. I haven't read the others. However, Facebook friends/family in Arkansas, Missouri, and around Texas from about Dallas to Wichita Falls felt it.
It's so strange to me that we're 200 miles away and felt it. There was no mistaking what it was.
