As you exit the Big Thunder Mountain Railroad look for the bed of cactus’s.  If you look carefully you can find some classic hidden mickeys.  You will find a large circle and two symmetric  circles above it.

You be the judge if this was on purpose or just coincidence.

 There is a hidden mickey that can be found as you ride on Big Thunder Mountain Railroad.  Pay attention as you climb the second mountain on the left side.  You will spot three large gears placed perfectly to form a classic upside-down hidden mickey.
