The inaugural festivities for the 45th President of the United States have been underway since yesterday, and at least 65,844,954 Americans are just thinking about how lucky they were to have the last eight years. So we bring you some memories from that very cold day-also a January 20—in 2009:

– Here’s the Obamas walking in the parade:
