Today I had the complete great plains experience: Endless prairie, Hot sun; Thunder storm; Hail; Flash flood; Tornado. Ok it wasn't that bad, I crossed about 80 miles of perfectly flat, golf course like prairie, had breakfast at Wall Drug (if you have to ask you won't understand), went for a hike in Badlands National Park, all in the hot sun without a cloud in the sky. As I was headed for Jewel Cave National Monument, I got the emergency broadcast signal right in the middle of a song, (I'd never heard it as anything other than a test). "Torenado warning, everyone in these areas go to your shelter". Two questions: 1) What shelter, I don't even have the top up; 2) Where are those areas (ie Am I in one)? Next cross road I figure out I'm in the middle of it. I can see a storm ahead, but it's still 80 degrees and sunny, and there is nowhere nearby to take shelter, so I keep driving, thinking that if I see something coming I'll pull under an overpass. I never saw a tornado, although I heard on the radio that it did touch down. So after the tornado warning expired I had a flash flood warning, an extreme thunder storm warning, a hail warning, and a tornado watch. So far the only one I've actually seen is the extreme thunder storm, which is extreme, and still going on. Anyway I decided these were not conditions conducive to camping, so I'm in a hotel. I didn't make it to Jewel Cave in time, so tomorrow morning is Jewel Cave, Wind Cave, Mt Rushmore, and Crazy Horse...
