Walk in Access is on a first come first served basis. No need to find or contact the land owner. If you are looking to take a "pure" Rio's, that could be tough. The birds in the N.C. area of Kansas seem to be a hybrid of Rio/Merriams/and or Eastern depending on how far east you go. Some look like Rio's, some look like Merriams, some look like a cross. Lots of birds to be worked out there though! I've hunted around the Mankato KS. area the past couple of years and that is what I have seen around there.
