The White House released never-before-seen footage of President Obama's family trip to Yellowstone National Park in the summer of 2009, continuing a long-standing tradition of presidents visiting the park. Chester A. Arthur was the first president to visit it in 1883, and the last one before Obama was Bill Clinton in 1995.
"The notion that collectively we come together and we say, we're gonna preserve some things that last beyond our individual lives, that we're gonna pass that on ... that's part of hopefully what is best about our government," Obama said.
