I needed to come up with something to fill a three inch or so wide gap between two structures.  As always the challenge is to find something that doesn’t look too “model railroady” which is often what we (I) end up with when left to my imagination.  A scan through my files of my site visit last year turned up this interesting corrugated steel fence with a door and razor wire on top. Just as with my layout the fence/barricade spans the back of two buildings.   Problem solved.  I’ve uploaded the artwork in the Photo Wallpaper section of the “How To” area.  In HO this should be printed out at 1.3 inches tall.
