Black Pipe

I was a little late to my swimming session this evening 

because I saw some pictures that needed to be taken.

Across the street from the IUPUI Natatorium, 

black pipe had been laid out and stacked,

ready to be laid for new water lines.

I remember when my ex and I would go to 

the hardware store to buy black iron pipe

for plumbing for a number of home projects. 

That has been replaced over the years,

but I don't know what material was

used to produce this pipe,

though it looked to be some sort of

synthetic fibre.
