Summer of '72 I'm driving from KCMO to Manhattan, KS on I-70, when the sky gets dark and starts to turn green. Twister! Turn off the music and I can hear the old air-raid sirens used for tornado warnings in the mid-West. I spot an overpass ahead and go for it. Put the car in the ditch and run under the overpass and up the slanted side to get right up under the roadway.
Here it comes! Really does sound like a big freight train. Five minutes later it's gone. Twenty minutes later the sun is out and the sky is blue.
Car had a cracked passenger side window. Nobody was hurt. Got back in the car and finished the trip.
Maybe the clip above is correct for straight sided overpasses, not for slanted sided.
