Here's the Order of the Parade Procession: Army First, NASA Last, Washington Post
"The Presidential Inaugural Committee released the order that the parade procession will march down the 1.5-mile path along Pennsylvania Avenue from the Capitol to the White House tomorrow. Over 10,000 people from all 50 states will follow Barack Obama and Joseph Biden along the route. Reps from the U.S. Army and Reserves will lead off, and a contingent from NASA will bring up the rear."
"We'll be somewhere near the end," said Ferguson. "We were told not right behind the horses, but close."
