Bradw, I rode the Katy trail twice this year. First in April attempting the Lewis and Clark (leg 1) Trail. Part of my tour included the Katy Trail from St. Charles (awesome town) to Boonville. I also found some washed out sections and the trail did shake my bike loose. My headset loosened and I replaced my bottom bracket. The only thing I had trouble in April's ride was finding places to pitch my tent. All of the info I read before the ride told me NO CAMPING on the trail.
Last weekend I rode the trail from Clinton to Rocheport. I pitched my tent any place I found flat grassy space. Actually, the winery let me pitch my tent in their backyard! It was easier to find my 'home' after a few glasses of wine! Just curious if you had any troubles finding camping space. Did you try to stick to campgrounds?
Nice thread.
