[Editor's note: On Inauguration Day I maintained a live map plotting which parking garages were filling up, where metro trains were getting crowded, and tracking which areas of the National Mall people were flocking to or being blocked from. Information was filed both by staff reporters via a huge group email list and by tips email or texted in by readers. The map was updated around 50 times from 4 a.m. to 6:30 p.m., Gene Thorp filled the afternoon shift. In a fast changing event, currency is important so we time-stamped all the data points. Next time I need a way for older entrees to fade off the map automatically.]
