In April, an 11-year-old named Rebecca wrote to President Barack Obama saying her heart was broken because he had yet to visit her state of South Dakota. She even pointed out some of the sights he could see there, like Mount Rushmore and coyotes.
On Friday Rebecca's wish will come true.
The president will give the commencement address at Lake Area Technical Institute's graduation ceremony in Watertown, South Dakota on Friday.
The Argus-Leader reports the last time a U.S. president visited the Mount Rushmore State was 13 years ago in 2002, when George W. Bush helped drum up support for Senator John Thune.
Obama will have achieved a milestone only a handful of other presidents have with his trip, having visited all 50 states during his time in office.
Both Bill Clinton and George H.W. Bush made it to all 50, which is pretty impressive when you take into account that Bush only served one term in office. George W. Bush never visited Vermont, therefore narrowly missing that 50-state mark.
