I just came across my namesake from the land of OZ,written by Brad H.
Brad has been blogging a few years longer than I and enjoys the experience of attending model railroad exhibitions, something not happening here in the hot and dry area of SW Arizona. He has a long list of layouts visited at such exhibitions and a lot of ideas for portable layouts, also not seen much in the SW USA, excluding the module type. Drop by Brads site and say hello. Search for " armchair modeling downunder " and work from there. I can't get it to link right now.
