On our maiden voyage last year we were on the Ohio turnpike when our weather radio went crazy with a tornado warning. We had an earlier warning as well, so we saw a pull-off and hunkered down. We both made sure our seatbelts were fastened, and were ready for our entire rig to blow over in the ditch to our right. The van and trailer swayed like a amusement park ride. Everytime a tractor-trailer slowed down next to us, we were hoping they would just stop to buffer the wind. We survived, but are very glad we had that radio, and that we actually paid attention and hunkered down.
