During shows, Andy will clean and lubricate engines for members. It has a work area (grey scribed area), a soldering station, and the layout features Andy's custom made buildings and switches.
Not everyone does modules. Harold and Thea Oakley like European trains and have a number of layouts at home.
Most of their home layouts are just too big to bring to shows.
Jim Glass helped get the BYOZ (Bring Your Own Z) started. BYOZ allows people with small, tabletop layouts carry in their layouts to a show and run them as long as they want.
MicroTrain Geeps are just the latest in affordable Z scale power.
