Tornado Safety

A few years ago friends of ours, in a very large new camper parked overnite on their way home from a gathering we had been at with them that week. Can't remember if they stopped to overnight in a Cabela's or a Campers World parking lot. Their camper was hitched to their heavy tow vehicle. While asleep the tornado sirens went off and he stood up from bed and that's all either of them can remember. Their camper was rolled many times and totally demolished, but somehow they both survived with just broken bones and cuts. It was the weight of their tow vehicle that keep their camper from flying off. There were a few other campers overnighting there too, but not everyone was so lucky. Luckily it was the edge winds that hit that parking lot which is why they are both alive. (someone in another camper died). They thought they lost their cat but the next day it came crawling out of their totally flattened camper. So even though the chances of ever being hit by a tornado is low, it could happen. Please use common sense and get inside a concrete building if possible. Don't stay inside a camper, they blow apart or are totally flattened. By the way because the camper was attached to their vehicle the vehicle insurance helped pay and they were able to buy a brand new just as fancy camper as the one they lost. He said if they had unhooked it from the vehicle they would have received less insurance money (plus they would have probably died). My choice between being in a camper and a large vehicle is choose the vehicle if you have no other choice. Please use common sense and try to get into an underground or concrete shelter if you have any time. And always travel with an emergency weather radio (that would have alerted them sooner).
