This clinic is useful to ALL modelers, regardless of scale. The clinic will cover all the items that need to be documented. It will cover what to document and how to document it, for example; wiring, inventory, and other items that concern your layout that you need to have handy in an emergency. Do you know how much your model railroad is worth if you had to replace it? Do you remember how you wired the diode matrix for the yard or where all the isolated rail joints are? If you answered 'NO' to these questions, then you should attend this clinic
