I found a fun site relating to the American Presidency. It is Pat's Presidential Places. It features pictures of the gravesites of U.S. Presidents, Vice Presidents, presidential and vice-presidential election losers. It also has the gravesites of some New York State Governors.
The site is a bit hard to navigate as it is laid out somewhat haphazardly. The picture of Wilson's grave is still missing too. Despite this, I enjoyed the site and found it fun.
