Caching supplies

I think I've found a good spot to preposition a few things in case I can't get to my main stash for whatever reason(s). Behind my home is a fairly large cemetery, which is next to a convent. The best part is that 2/3 of the land is overgrown with trees and brush and pretty much has been left alone by the owners. Now I don't see the cemetery rapidly expanding in the near future, and I think I can stash my equipment with little difficulty.
