Stop in for a cup of coffee

i'd love to have a good tornado shelter. dodged too many in a hallway recently. but i doubt i could afford them, they want nearly 20k for them
Dig a hole in the ground, drop a shipping container in it so that it’s 2’ below grade and cover with dirt. Add a set of steps down to a door and put a closable steel cover over the stairs along with a couple of fresh air vents. Instant tornado shelter.

Also doubles as a nice root cellar.
