Thanks, guys! The Backroads Touring - Kansas site has this to say about the 100,000 miles of "secondary and unpaved roads" that they ride:
We consider ourselves most fortunate to have access to the tallgrass prairie and other unique areas of Kansas, and are committed to leaving those areas just as we found them. To those folks who live where we travel to .... we are pledged to "tread softly and leave nothing behind". As a group, we only ride public access roads and do not ride on private roads without permission. When we cross unfenced open rangeland via public roads, we will remain on the roadbed so as to not cause possible damage to the prairie or raise the ire of landowners. We will also take precaution to not "spook" roaming herds of livestock when riding through open range areas.
