Silver Brook Cemetery, where the cache is located, is only a mile or two detour from my route to work. When I got there, I met bpp_picnic, who'd just found that cache. Then I searched for it too and found it.
When I got back to the computer, I pulled up my long list of geocache logs and easily found the required 50 caches. In fact, I came up with 60 without too much work. And so I logged the challenge cache. The worst misspelling I came across was "cementary". It sounded like a collection of cement. :)
