Ballast by the tonne.

Crew were walking around in mud, puddles everywhere when it rained... it was high time to ballast
Alexandra yard.
I mixed a few different colours from my supply of gravel, until I was satisfied that it approximated
the look of an old yard. I will still apply oil and soot here and there - and a lot of weeds!
I used Woodland Scenics cement, but I could have used diluted white glue - much cheaper...

I'm satisfied with the look though.
