It is a sereen cornfield with a little shed. But deep underground, in the abandoned mineshafts, Apature Science is using the new "vehicle teleportation track" to test how moving vehicles are behaving while traveling trough portals.

The AI GLaDOS and a couple of personality (manti)Cores are making sure everything is going to plan.
If the test is succesfull there will be CAKE!!
