How can I overlay a VFR sectional on another map to identify features and landmarks?
Seems to me you're going to be directed by SoCal approach that whole route per the routing shown in Skyvector.com, especially with the LAX Class B right there, and the TFR will be the last of your worries. Put your enroute and the final destination into your GPS (Foreflight or whatever), and be ready for deviations.
