Mark this day as it is the first time in 2 decades I ever complete ballast and ground cover on any layout I ever built.
Ballast is a mix of various dirt, sand, sandblasting sand and charcoal. It's only a starting point as I'll have to adjust coloration here and there with washes, pastel powders and various material. Harlem Station was a very dirty place to be. Some weeds will also be needed here and there.
