I'll be ordering my first HO train set this week sometime. I'm ordering a set because i'm cheap, don't have a clue, and would like to get a small simple layout up and running for christmas. Anyhow I've been lurking here for a while and am blown away by some of the layouts i've seen. Can anyone please direct me to a site or sites that have some detailed tutorials outlining diy construction of landscape elements? Trees, rocks, groundcover, building construction, and water...stuff like that. Thanks.
