The grounds are located east of I-55 at the Hernando exit. Not really sure what exit that is. But go east from I-55 to McInvale rd., go right, it looks as if that turn into Holly Spring Rd. The next rd you come upto will be Getwell. Go past get well .6 miles and the grounds will be on the left.
I am sure signs will be put out once you get of I-55 and go east.
