If you take I-35 South to Oklahoma City, then the HE Bailey Turnpike to Lawton that is about halfway - it is about 835 miles from KC to Houston and Lawton is halfway on that route. You can also take I-35 to Dallas and going that way Ardmore, OK is about half way - maybe a few miles short of halfway.
