So it might run a little something like this...
New visitor: So what's with the name on the monorail?
Repeat visitor: Walt Disney World is the park, and this is the Monorail System.
New visitor: No, not that one. They put someone's name on the nosecone. Who's that?
Repeat visitor: Oh. That's someone who died in an accident with the monorails.
New visitor: People die on these things?
Repeat visitor: It was an accident, there was a collision --
New visitor: These things collide?!
At this point, sentimentality over monorails isn't going to help our informative repeat visitor salvage the conversation. (Neither will, "well, collisions happen sometimes!") Better, perhaps, not to put the names on the new models...
