Goudacat: We visited the area and sure enough, both rust buckets are gone. Amazingly enough, the cache container was still there, hidden under some wood at the base of the closest tree. We retrieved the container so we can re-hide it somewhere else.
Those two rust buckets have probably been there for decades. Hard to believe that we put a cache in one and they are hauled off within a matter of months. (Not that we are complaining, they should not have been there in the first place.)
Thanks to everybody who visited the cache, especially lucyandrickie who rehid the container for us and logscaler and Red who notified us that the rust buckets had been hauled off.
