Stop in for a cup of coffee
Yeah, I lived in Memphis and still have a house there. I know all about the joys of living in tornado alley.
I picked that house based on terrain and placement. In 2010 we dodged 23 tornadoes in 24 hours in that area ranging from F1- F4 and while others lost their roofs and/or second floors on the ridge above us...we didn’t lose a shingle. The Mall 5 miles away was totally destroyed and the shops 2 miles away were also wrecked.
After that, we had a safe room built under the central staircase anchored deeply to the slab with 1/4” steel cladding welded together. Was supposedly designed and guaranteed to withstand a prolonged F5.
Although, I have no idea how you could ever collect on the guarantee if it failed. I just had to trust my engineering knowlege that it seemed like it would do what they claimed.
