How old are these? Were they part of the safety overhaul that DL seemingly went through (the signs on every car of every ride, etc)? Or just an embrace of the bilingual nature of California?
Back in 95 (I think), when I was last at DL the only rides with more than one language warning spiels was the Matterhorn and it's a small world, as far as I remember.
I was especially struck by the one in the HM which was really creepy because going from Paul Frees deep spooky voice to a whispering Spanish voice is quit the shock.
