Personally, I love the generator in Indy's Q. I love listening to it sputter and stall and watching the lights dim through the ride. At night, I would say the best part of Indy is the Q. Simply great stuff! Thats one thing that I love about Disney rides is they try and entertain you as you wait. Star Tours little robots, Roger Rabbits unfolding story, Indy's adventure through a forgotten temple. Simply AWESOME! It helps kill the time.
Speaking of ST, I love the little robots scurring around the junk piles. If you look close, they are just model trains with lights stuck on them
