The River Styx

Junk rafts carry souls along the River Styx between the Blue Tunnel and the Pearly Gates

"To go through the Pearly Gates, no matter how tempting the interviewee on the other side, as I myself discovered the hard way, is to run the risk that crotchety Saint Peter, depending on his mood, may never let you out again. Think of how heartbroken your friends and relatives would be if, by going through the Pearly Gates to talk to Napoleon, say, you in effect committed suicide."

~ Kurt Vonnegut
