Four or five million Obama supporters in a confined space sounds -- "interesting". Best place to be on Jan 20 is far away from DC.
just checking on hotel rooms. They say there are 1000 rooms available in the DC region, most at $1,000 per night (and virtually all of them with a 4 day minimum stay). I have a tent and you can use my bathroom to freshenup ~ $250 per day, 3 day max. (/sarc) See: http://www.wtop.com/?nid=780&sid=1539390
