San Carlos Cemetery
I have driven by the San Carols Cemetery countless times and but never stopped. It appears to be pretty old but there are quite a few new headstones there are as well. I saw headstones there as recent as 2009. I didn’t go very far in so there my be newer than that. The oldest I saw was from 1923.  

There is only one tiny road through the cemetery and I didn’t feel comfortable trying to drive in there.
