Enter the cemetery through the northern entrance, on 11th Avenue(this entrance puts you on the cemetery's Center Street, which runs N-S).
The plot is at the corner of Center Street and 310 North.
The plot is located at the northwest corner of that intersection.
The McAllister plot is not readily seen from the road because right next to the road is a grassy knoll (I was given these directions in these terms - let's leave conspiracy theories out of this). You have to walk over that knoll before you see the Richard Wesley headstone.
