|Steve Bennet's Gn15 Black Cat Mine is a derivative of of his 00 Black Dog Mine layout. Steve, by the way, is one of the developers of Gn15 and supplies an ever increasing number of loco body and stock kits. (See Pepper7 in Links). His mine is based in an area with a lot of arsenic in the soil so minimal vegetation! Being a lazy soul I decided to base my layout on his but flipped it and made the depth slightly greater. Thank you Steve.
