Here's our little cabin. It had satellite TV, so we didn't really "rough it." The beds were a little firm, so those with delicate backs probably should look elsewhere. Great for an inexpensive couple of days away, though.
The state park itself is really beautiful. You don't really think of Oklahoma as covered in trees and hills, but Eastern Oklahoma is really beautiful. Even in February.
The drive down there took us through Tahlequah, OK and dinner at the Oklahoma institution: Del Rancho (home of the Steak Sandwich Supreme.) Sharon fell in love with Del Rancho on the first visit, so another visit had to occur on the way home. Here's the famous Del Rancho. Basically unchanged since 1959.
