Space Shuttle Endeavor which is going to the LA California Science Center is going to be doing flyovers in different major cities and over NASA sites on the way from Florida to LA.
So far I know its going to flyover Houston and stop at JSC/Ellington for the 17th and 18th of September, I know its going to flyover El Paso/Las Cruces, then on to California where it will fly up to Dryden (19th) then go to San Fransisco and back to LAX (20th)
But from what I hear there is going to be plenty of photo-ops in Houston as its going to fly around downtown
