Have you read the original gondola thread? Someone even complained that they wouldn't ride because they were afraid of STARVING TO DEATH. (I'm hoping they were kidding, but it was hard to tell.)
There was also someone complaining that the gondola cars don't blend in seamlessly with the sky.
This thread is so people can let loose. @Lensman is good people.
Mostly not valid. I feel like cannibalism would set in after 3-4 hours and it would be easy to roast meat in the hot boxes.
They will try some Gondola Cabins without walls, floors, or ceilings so that the blending in with the sky will work perfectly.
