As they say, all roads lead to Rome (though this is not true anymore, most of them wind up in California). The last road in the universe peters out at Penatrata.

As you can see by the quantity of debris that lines it, this road has been well-travelled by humankind. Some (but not all) of the broken bottles come from the Tyson twins shooting competition. When I asked the twins about the burnt out zeppelin sticking out of the sand dune, they refered vaguely to "the freeholders' revolt", and refused to say any more.

And such poignancy, if you ever wondered how far the Energizer bunny got, he almost made it to the very, very end!
