Good advise
click here.If in a campground, the bath house is usually the safest place. You don't want to stay inside your camper, as it can get tossed around like a tinker toy and destroyed.
If you know positively a tornado is heading right at you, and no where to go, look for the lowest spot and get in it and forget your dignity. Get your face in the mud and lay flat.
You never stay inside a vehicle. Always get out, look for a ditch a culvert, any place near water (lake, pond, river and find the low spot.
Keep insurance up on your vehicle and camper, and if indeed a tornado is heading right at you ... the camper can always be replaced, but you or your loved ones cannot! Get out, and literally .... hit the dirt!
Overpasses are not safe either. The tremendous force of a tornado going over or through an overpass, and you're under it, could suck you right out. It's like the hose of a vacuum sweeper, you run the risk of being sucked out! Very dangerous.
But the odds of YOU running into a tornado are very slim. Don't give it a second thought and enjoy your trip. You could stay home and slip and miss a step on your front porch, fall down, bust your head and be killed instantly. Does that mean you stop using the steps of your front porch. If you live in the "what if" world, you'll never enjoy life.
And remember, the natural elements of the weather are very much a part of the camping experience. Adverse weather creates new opportunities for creative camping techniques. It's not always a sunny day in the mid 80's you know. Embrace the magnificent forces of nature. It helps keep a perspective of the real values of life.
