Night of a 1000 Trains

In the "credits" section of the poster it reads...

Tornadoes have often been said to sound like a thousand locomotives or planes. If a tornado threatens, follow these safety rules:

In homes and small buildings, go to the inner-most part of the lowest level.
Stay away from windows and outside walls, interior closets, halls, and bathrooms are good places to go.
If you do not have time to get to the lowest level, get under something sturdy like a bed.
In school? get under your desk.
Abandon mobile homes, cars, and trucks. get into firmly built shelter. if none is available, lie flat in a low spot, ravine, or culvert with your hands protecting your head.
Finally, avoid using bridges and overpasses FOR shelter. stopping under bridges and overpasses only leads to traffic jams and the possibility of a greater number of injuries than what would have otherwise occurred.

Dispelling some common tornado myths:

Decreasing the air pressure in a house by opening a window does nothing to decrease the DAMAGE. Even the strongest tornadoes (EF5 of the Enhanced Fujita scale) do not reduce the air pressure low enough to cause a house to "explode". Leave the windows alone. The tornado will open them for you.
The southwest corner of a basement is not the safest place to be in a tornado. Actually, the worst place to be is on the side from which the tornado is approaching...usually the south or southwest.
You are safer outside of your automobile than inside. The high wind of a tornado can blow your car around much like you can with a wad of paper.
Bridges and overpasses are not safe places to be in a tornado. You are higher above the ground, in the stronger wind, and are in the path where most flying debris occurs.
