My husband and I are flying to Las Vegas from Memphis to go on a rafting trip in the Grand Canyon. From Las Vegas we will be driving to Oklahoma City in a rental car to visit friends. My question is I need help planning what to see from Las Vegas to Oklahoma City. We will leave Las Vegas on May 28 and plan to be in Oklahoma City June 1st. I am a little overwhelmed with where to go. I know there is a lot of America between the two places. Any help would be greatly appreciated.
