Lots of varied circumstances today. Started out with lots of hills, wandered through some nice farms to the edge of the urban center. Went from farms to subdivisions quite abruptly. Nice lunch in St. Charles, launching point for Lewis and Clark. Rode through Ferguson on the way into St. L. Interesting - physically more prosperous than some parts of Chicago, but a pretty bleak street scene. Joined a nice path north of St. Louis along the river, all the way into town. First glimpse of the Arch was quite exciting. Marked the half way mark!!!!!!!!!!!!!
