I used "Starter Chicken Grit" bought at a local feed store. I dyed some dark and mixed it so I have three batches of light, dark, and a mix of both. This way I can use it where traffic demands. As for most of my Utacolzona On30, I also put down a lot of dirt, coal, & grass effects. Everything is glued. Dennis
This picture is the final stages of track work before all the scenery.
