I see that no one else is still concerned with this (or if they are they aren't posting) and i've been doing a bit of research...I dunno if it'll do anything for anybody, but it seems that the book "Death of a Traveling Salesman" was written by Eudora Welty, and it involved a shoe salesman that...well heres a synopsis:

Anyways, it talks about when he dies, he dies on a highway (one or two of the pictures was a highway) and it also talks about dying alone/being alone in life (i believe that one of the prompts had something to do with this)...didn't know if maybe that had to do with anything.
just tryin to bring some life back into this thread!
