Yep, I remember it well. 500' from our house. A swath came through Rowlett after it blew cars off the 190 and I30 overpass. It was a bad one.

Saw where 6 were killed, 3 in Clarksville and 3 in Nashville.

I remember watching that one on radar, one came close up here that night from the same storm, wild night for sure.
