If you have never toured the planes that Elvis used to use, better get to Graceland before next spring.The planes have been on tour across the street from the Graceland Mansion for over 30 years. The Lisa Marie and Hound Dog II were sold to the company after Presley's death back in 1977. They agreed to keep them on the Graceland Grounds for tourists.

However, the people who operate Graceland have told the airplane owners to be ready to move the planes by next Spring.

Now definitive word on what may go in that space, but something retail related for tourists is expected.
