Many presidents’ accomplishments have passed into folklore, such as George Washington’s dismantling of a cherry tree or Lyndon B. Johnson’s discovery of the Ark of the Covenant. Celebrate the feats of a former head of state with today's Groupon: for $9, you get one admission and one GuideCam tour at the Ronald Reagan Presidential Library and Museum in Simi Valley (a $19 value). Kids 10 and younger are admitted free.

Ronald Reagan Presidential Library and Museum chronicles the life and career of President Reagan on a sprawling, 100-acre Simi Valley campus. The museum's more than 100,000 square feet of exhibits, including an Oval Office replica and President Reagan's gravesite, draws in history buffs and provides children with an often-interactive primer to America’s 40th president and the 1976 winner of the Iditarod. Visitors can use the museum’s GuideCam handheld device to take still photos and video that are instantly forwarded to the visitor's email address or preferred social network. Headphones allow private immersion in the background of exhibits such as Reagan's actual Air Force One and a piece of the Berlin Wall. Examining all the exhibits usually takes about three hours, though Gipper gawkers can rest and refuel at the Ronald Reagan Pub housed within the museum, which features sandwiches, beverages, and a vintage Walter Mondale dartboard.
