I think I was most amazed by the the wide open spaces we saw as we traveled along the highways. Yes, we saw miles and miles of corn fields and mile after mile of fields where the hay had been bundled up for the winter. But there was also miles and miles of gently rolling hills and verdant valleys. We were reminded of pictures from our childhood history books of the pioneers and their wagons trekking West. I don't think it has changed much except the herds with thousands of buffalo have disappeared and so have the never-ending flocks of birds. One is very aware of how small we are when confronted with these vast spaces. It was beautiful and so varied in texture and flora.
