I read Roger's Web site thoroughly a year or two ago, and had to email him at the time about how impressed I was. I know of guys who have dug out crawl spaces for layouts, and one fellow who dug out a whole basement starting on his stomach with a searving spoon. But cutting through rock I'd unbelievable!
the layout itself is fantastic in its own right. Thank you OGR for publishing this article that gives more insight!
Thank you Roger for the inspiration to build a layout and the inspiration of the double meaning of your layout name!
