Big Smoke's

Well stacked pizza co.

Also I'm looking for well thought out opinions on the pros and cons of placing these electrical pylons in this area.

I can't help but want to fill in this area because it will be longer than just this - and the angle means I can't put much else there, but a con that I might not be understanding is that electrical pylons are mainly a rural thing.
In the actual game, this area isn't empty like it is here, this is the only compromise I can think of.
EDIT: Humble beginnings of my conversion of the map to a 2D minimap for use in my GUI.

The X axis is a bit backwards atm :P
