Our safe room is in the garage so we just have to step out to it and not outside. My wife and kids took shelter in it the same day as the Moore tragedy due to a warning in Washington county. We kept our kids home that day due to the what they were predicting. I am glad we did but my wife was sick all day because she forgot they were at home and was worried they were at school.
Ours is rated for an EF-5 as well but I pray I never have to find out to confirm that.
Make sure your "safe room" is registered so the 1st Responder's will know where to dig you out. Also, make sure you have a bucket, toilet paper, wet wipes, snacks, and bottled water. You may very well be stuck in there for a couple days if your house collapses on it.
