Yep! Thats it!
And the other one I think is the original (now old) Nappa Marrie Strip.
Some of the old....errrrrr more experienced folk here might confirm this.
When I first went there I tracked for the original one......and I should point out the one in your Jepp data base on all your GPS's is the old strip about 6 NM away from the homestead, and I flew from Coober almost over the Dig Tree, saw the homestead and having been warned then went back to find the Dig Tree.
WAC's and even the current Jepps are so far out of date with some things like this it pays to ask someone who has been, or you would be a bit disapointed
Actually the latest Google Eart shows the old strip with a white cross at the intersection........must mean gliders or parachutes or sumfink!
