The Leprechauns: This area is now a dog park, so replacing the cache would make for bad interactions with muggles and doggles. Also, since the cache was hidden it now has an urban magnet school as a neighbor across the street. Final nail in the coffin was a stabbing that occurred near the cache area - unsavory characters roam the area at times when geocachers are likely to visit. Time to put this old, old cache to rest in the archives.
