I see many references to MR Video Plus series where Cody showed some ballasting techniques:

Chips88 I also remember he was using Smith Sons Ballast.
I live about a half-mile from where Harley and Dale Smith had their ballast buisness and layout. Sadly both are now deceased. Scenic Express carried their ballast for a while. Arizona Rock & Mineral is one of the best sources for real stone ballast. Even Highball is long gone.

Ladies/Gents - I am looking for an article written by Cody Grivno where he was showing us how to ballast and completely cover a yard in sand. I believe he had an old photo of an ATSF yard out in California as an example. I also remember he was using Smith Sons Ballast. I can't remember if it was in "Model Railroader" or one of the special issues. Can anyone help me?
