My friend works for Cultural Tourism DC, who plans Passport DC every year. It’s pretty awesome.
via A Guide to the Passport DC Embassy Open House – washingtonpost.com:
One of the wonderful things about Washington is that it is full of embassies. On Saturday, more than 25 of them will open their doors to the public for a day of festivities as part of Passport DC Open House. You can visit embassies by neighborhood or just choose your favorite; either way, this is your chance to get into another country and have a look around for free. All open houses are from 10 a.m. to 4 p.m. unless otherwise noted.
