After over 3 years, (since Aug 2005) I am getting back into my model railroad activities and back to reading and posting at the Gauge. I will begin planning the rebuilding of my layout that Katrina's rains ended. Water and layouts don't mix well. Spared portions of the layout have been stored vertically for years now so I guess I will start new and try to save some of the landscape elements. I am going to try to do DCC rather than the block system. Don't know anything about DCC, any suggested books to read up on the basics?
