i was surprised to find out that you left out the fact that sneakers being hung from power lines usually and generally means someone has been murdered or has died. its common tradition in inner city urban areas, and parts of big cities with high volumes of violence to toss the shoes of those taken away.
“The fact”? Bollocks. It may conceivably mean that on occasion, but it would “usually and generally” mean that some bored dude had an old pair of sneakers and thought it was a cool thing to do with them, having seen it like a million times before.
I mentioned this in a previous thread on the topic in my first days at the SDMB, but, inspired by Cecil’s article, I visited the Arkansas show tree when I went to Arkansas a few years ago. I looked it up again and I see to my great dismay that the tree is no more (knocked down by a rainstorm on 6 May 2000)! But there are others.
