Wow, thanks for that trip report, it was a walk down memory lane for me in more than one way. For one my first wife grew up about 20 miles form Van Buren, MO in the little town of Winona which you would pass through if you were driving west from Van Buren. Also I drove through Greensburg KS, in the summer of 2007, just about 8 weeks after the tornado hit, the devastation was hard to comprehend, starting about 7 miles out of town we started seeing wind damage, it got worse and worse as we approached the town, there were no undamaged building to be seen, and several blocks were just piles of debris, even the street signs were gone and the street names were painted on the pavement in spray paint so people could tell which street was which.
