I confess that I haven’t read Slaughterhouse Five (yet), but I do still know about Vonnegut’s use of So It Goes. miles to go (I believe it’s supposed to be lower case) chose to pair the phrase with a bomb representing the Dresden bombings, which is a bit of a sad statement. It’s a sad statement that still, admittedly, looks pretty cool on a t-shirt.
You can buy it for $18.00 at the miles to go store if you wear either the medium or large sizes that are still in stock. The print is a tad bit wavy at the top, which gets you a $7 discount (the other version is $25.00).
