We used our daughter's college Spring Break to go down to Oklahoma. The eastern part of the State has plenty of lakes and hills and trees, etc. We wanted to get in some hiking, rapelling and top-roping. Kansas is rather vertically challenged and places to use our ropes and gear are minimal. We don't do anything radical and we don't do technical climbing. We rented a cabin at Lake Eufaula and drove to Robbers Cave State Park for the fun stuff. Never been to either place and I'd go back again.
