The Census Tiger Mapping Service
I'm not sure why I didn't know about this sooner, but the US Census Bureau has an online mapping service called Tiger that let's you input coordinates for places of interest as well as other mapping functions (like grids, regions, etc.) The service can map metro areas (here's a map of the Capitol mall the with White House and Capitol marked) or larger areas (here's a region with major cities marked). As they say on the site, this isn't intended to be a production quality Web service, so don't use it like one. But for quick maps of data, its very handy.
