Traveling in Tornado prone areas

We check the weather 10 days ahead and try to avoid storms if possible by taking an alternate route or staying put another day or two. I check www.weather.com every day. We have a weather radio and leave the setting on "all" counties. When we stop, I find out what county we're in and note the surrounding counties. I ask the park office were the shelter is. If there is a severe thunderstorm warning with high winds or tornado warning, we go to the shelter. In 5 years of traveling, we've only had to do that twice. Once outside Cincinnati and once in Florida!
