I drove through part of that weather pattern on my way from Indiana to the east side of Cincy that morning. Was just light snow blowing across the road but you could see where it might get slick in a hurry. Whiteout never crossed my mind. Didn't think much of it. Was westbound after lunch to go north when a buddy called and told me to take a different route. My wife was shoe shopping (go figure...) off Colerain avenue at the time. Called her - she was trying to get on the highway but traffic was stopped. I re-routed her. Never thought I would say this, but I guess I'm still thankful she went to one more store to find the right shoes.
As for why they got out of the car.... I guess I would have too. I won't post the accident pics, but you can find them on the local news sites. No way I would have stayed in one of those cars. From what I heard the hits just kept coming.
Sad day indeed.... can't begin to imagine burying my 12 yr old.
