The Political Graveyard
This is an interesting site: a database of graveyards where USAn politicians are buried. "Politician" is construed very broadly, to include, e.g., ambassadors. One tidbit: the graveyard in Sleepy Hollow, NY, not only holds the grave of Washington Irving (of course), but also that of Carl Schurz, one of my political heroes. Maybe a pilgrimage is in order.
