President Obama gets the chance to shake hands Friday with some of the operatives who helped take down Osama bin Laden.
He'll meet privately with them at Fort Campbell, Kentucky, where he'll also address soldiers just back from Afghanistan.
Thursday, the President was in New York City offering a personal thank you to 9/11 first responders.
He later paid tribute to the victims at Ground Zero... and met with some of their families.
Intel gathered from Bin Laden's compound show Al-Queda was considering attacking U.S. trains on the tenth anniversary of 9/11. Memos reference a list of potential plots against major cities including New York, Los Angeles, Chicago and Washington DC.
Officials say the plans were wishful thinking if anything, and there's no evidence of any active plots.
Still - that's not enough to ease the minds of some commuters.
As the search for new terror plots continues more details are emerging about how officials tracked down bin Laden.
The CIA reportedly kept a safe house near his compound in Pakistan where a small team of spies conducted extensive surveillance for months.
Maintaining that safe house was apparently so expensive that the CIA had to ask Congress back in December to reallocate tens of millions of dollars to fund it.
