If you took public tranist to hell when you die, what would it be?

Spaceship into a black hole.

Simple, quick thought: A train through the Rockies.
Deep thought: Technically walking is a mode of transport in public. Imagine being told that your path to hell was a walk around the world; would you do it?

Train - during a football day and school has let out. Chocker block full of BO, loud noise, complete lack of personal space and no end in site. That would be hell.
