More than 30 embassies and ambassador's residences will be open to the public as each country shows off its culture and traditions. There is so much free stuff to do -- sipping rum at the embassy of Trinidad and Tobago, listening to the sounds of the didgeridoo at the embassy of Australia -- that we picked 10 highlights you definitely won't want to miss. All events are Saturday from 10 a.m. to 4 p.m. unless otherwise noted.
