Corrected entry: When Rory is shown on the Hoover Dam, running to the edge, twice you see the Mike O' Callaghan/Pat Tillman Bridge. An impossibility as this scene takes place in 1969, and the bridge did not begin construction until February 2005.

Correction: Helpful on-screen text informs us that this is the Glen Canyon Dam in Arizona, not Nevada's Hoover Dam.
