The Bush administration has been history for seven weeks, and most of the ex-president's senior aides from his eight years in office -- with the notable exception of Karl Rove -- have stayed largely out of public sight. But many are quietly making their mark in the private sector.

For former Vice President Dick Cheney, post-political life will revolve largely around two activities: spending time with his grandchildren and fishing in Wyoming's rivers.

On Jan. 20, Cheney and his wife, Lynne, returned to Casper, Wyo., the small town in the western part of the state where he grew up.

"He's definitely looking forward to more time with the grandkids and enjoying the private life," a source close to Cheney told FOXNews.com, adding that the former vice president built a home in McLean, Va., and he plans to split time between the two states.

Cheney has acquired a BlackBerry since leaving office, the source said, and he's programmed his grandchildren's spring sports schedules into it.

In recent days the former vice president has held "small luncheons" to "invite people to talk about current events -- both on the economic front and on national security issues," the source said. "He follows what's happening very closely."

Cheney is expected to publish two memoirs focusing on his time in the White House and the 40 years he spent serving four presidents. The former vice president has signed with the Harry Walker Agency to pursue various speaking opportunities.

Condoleezza Rice is also reclaiming the life she had before joining the White House in 2001 as Bush's national security adviser and later secretary of state.

Rice has returned to Stanford University -- where she taught in 1981 and later served as provost -- to work as a senior fellow on public policy at the Hoover Institution and as a professor of political science, Rice's chief of staff, Colby Cooper told FOXNews.com.

Cooper said Rice is focused on addressing flaws in the country's education system, and she plans to devote much of her work on primary schooling.

The former top diplomat also plans to publish two books -- one on U.S. foreign policy and another on her parents' influence in her life as she grew up in segregated Alabama during the civil rights struggle, Cooper said.

Former White House Press Secretary Dana Perino returned last week from a four-week visit to South Africa, where she volunteered with her husband at an HIV-AIDS clinic funded by Bush's PEPFAR project.

"I left from Dulles Airport at 10 p.m. on January 20," Perino told FOXNews.com, saying she was inspired to become a more effective advocate for the relief program after visiting Africa with Bush in February 2008.

For Perino, the trip was as much a self-realization as a humanitarian undertaking.

"I think over time as press secretary, I developed a very thick skin and put a shell around my heart that hadn't really been there before," she said.

"There was one point during the time we were volunteering when my heart burst wide open and I realized that this is why I came here -- so I could remember who I was before."

Perino said she has no plans to work on a political campaign in 2012, but she hopes to strike a deal with a major news network to become an on-air contributor.

"I think I can be a Republican voice at a time when the Republican Party is getting its footing," she said, adding that she would like to put to rest misperceptions about Republican women.

"For a long time we have been misunderstood, and to borrow a word from George Bush, 'misunderestimated,'" Perino said.

George W. Bush himself has returned to Texas, and he and Laura Bush recently moved into a new home in Dallas, the first time they've lived full-time outside an executive mansion since 1994.

The former president has plenty to keep him busy: there's a library to build, books to be written and his mother's health to be monitored.

While Bush has been mum for the most part on President Obama's job performance, former Deputy Press Secretary Tony Fratto was out defending his old boss a week ago, and excoriating the new president for putting war funding into his annual budget request and criticizing the budgets of the previous administration.

"Our budgets were honest, open and transparent. Every dime spent was presented, debated, voted on and counted," Fratto told FOX News.

Other high-profile Bush administration aides have also returned to their roots.
