My buddy, Chris Myers, always sends me some of the neatest links or photos! We both submit memorials & photos to Find-A-Grave to help those who, for whatever reasons, can not visit relatives & ancestors graves (usually they live too far away). Many times people do not know where someone is buried, but you can search Find-A-Grave to see if you can find them across America. Now, you can search by state (we often know that they were buried near where they lived in a certain state). Not all states are included yet (17 to-date), but here is the link for what states are available:
