If you won’t be in D.C. for Barack Obama’s inauguration on Jan. 20, you have a chance to at least get a sense of what you’ll be missing earlier that month. The Post reported today that the official inaugural rehearsal date has been set for Jan. 11. The inauguration dress rehearsal, which features stand-ins for most of the VIPs, is done every year early in the morning on a Sunday before the inauguration. This year’s rehearsal runs from 5:30 a.m. to 9 a.m. that morning, and will allow the Armed Forces Inaugural Committee to run through the program twice in a row. The rehearsal will be open to the public, so if you feel like getting up early that morning, head down to Pennsylvania Ave. to catch a preview of some of the bands that will be playing in the inaugural parade.
