US President Barack Obama has fulfilled the dreams of a 11-year old girl, who penned him an adorable letter in April asking why he hadn't visited her beloved home state.

President Obama finally visited South Dakota yesterday, the only state he had not visited during his presidency, mending the broken heart of a young girl who was sad that he hadn't visited.

The girl, known only as Rebecca, from Vermillion, South Dakota, had her letter published on the White House Twitter account on Thursday, the day before Obama paid a visit to her state.

In the adorable letter, she writes: "We are the warmest of the Dakotas, we have Mount Rushmore, and when I just go to the park, I sometimes see coyotes, hawks, and bald eagles."

The letter ends with a note next to a picture of a broken heart, which reads: "This is my heart because you haven't visited South Dakota!!"

Her wishes were answered yesterday as Obama made a flying visit to the state, where he made a commencement address at Lake Area Tech Community College in Watertown.

After his speech, he was given a Lake Area Tech jacket, which he wore with pride as he left the stage.

Yesterday saw the President make a whistle-stop coast-to-coast trip across the country - starting the day in Oregon, in the Pacific Northwest, then heading to South Dakota, around 1,500 miles away, before heading back to the White House in the evening.

Obama's visit makes him part of an exclusive club of US Presidents who have visited every state in the Union - only Richard Nixon, George H.W Bush and Bill Clinton have accomplished the feat before.
